The computer freezes wildly, what's the problem? We fight viruses and clean the disk. Unnecessary applications in Windows startup

The computer freezes completely, Windows 7 stops responding to any commands, it’s even impossible to open the task manager? Such problems appear quite rarely. I must say that a computer is enough complex system, and its performance depends on a huge number of factors. The article will discuss the main ones. After reading, you will learn to cope with most of the problems that lead to “freezes” on your own.

Viruses

The first answer to the question of why the computer freezes is the simplest and most common. It is quite possible that uninvited guests have settled on your computer and are well camouflaged. Typically, viruses not only threaten the security of the system, but also significantly load computer resources. Sometimes this load causes the computer to freeze.

Everyone knows how to deal with such a scourge. It’s enough just to install any anti-virus program, update its databases to the latest ones and run full check computer. If it doesn’t help, call the task manager and check the processes to see if there are any suspicious ones. It would also be a good idea to look into startup by entering the name of the utility “msconfig” in the “Run” window.

However, if the computer freezes dead after turning on, it will not be possible to install new software, much less check the PC. In this case, use any antivirus distribution that can create bootable USB flash drive or CD.

Overheat

When releasing each new device model, manufacturers try to make it more sophisticated than the previous one. And this requires more power. The latter, in turn. increases heat generation. For a while standard system cooling does its job, but after a while its effectiveness decreases - as a result, the computer freezes completely. What to do if such a disaster happens?

Dust, which cannot be removed, clogs into radiators and interferes with air circulation. As dust settles on the cooler, it slows down the rotation speed of the propeller. Previously, such problems led to device failure. Today, fortunately, computers have become smarter; the processor or video card will not heat up endlessly. Modern devices have the ability to communicate with the motherboard, entrusting it with temperature control responsibilities. As soon as the values ​​reach a critical point, the controller first tries to unscrew the cooler screw, but if this does not help, the system slows down the device, reducing the voltage. Soon the computer freezes completely.

To prevent such troubles from happening, remember a few simple rules:

Very often, because of this problem, the computer freezes in games or other graphic applications. To check how hot your computer components are, you can download a program. Fortunately, there are a huge number of similar ones on the Internet.

RAM problems

RAM is the most important element of a computer, which has a very large impact on its performance. Normal operation of RAM depends on compatibility with the motherboard, BIOS, and other installed memory sticks. A minor glitch, the smallest manufacturing defect - and the computer freezes tightly when turned on, not wanting to work even at low performance.

If you are going to increase or change the RAM, fully study its characteristics, go to the website of its manufacturer and manufacturer in advance motherboard, learn what speeds are supported, what testing has been done, and whether it's recommended to use the devices together.

If your computer freezes before you change the configuration, you can check whether the problem is RAM, using Windows 7. Just click on the “Start” button and type “memory checker” in the search box. During the procedure, the program will display all errors if any were found. There is only one recommendation: if there are errors, change the memory.

HDD instability

A hard drive is a device on which absolutely all data (both user and system) is stored. Accordingly, Windows accesses it all the time, reading and writing does not stop for a minute. This means that system performance directly depends on the operating speed of this component. Over time, “broken” clusters and unreadable areas may appear on it, which will lead to system failures. Often, because of this problem, the computer freezes on the Internet, because while surfing the browser constantly records and deletes many small files.

Repairing a broken HDD

If the HDD is worn out, you need to check it with special software tools that will find all damaged sectors and mark them as non-working. The OS will stop using “bads” and stop freezing. To check, run command line by entering the name of the program in the “Run” window - “cmd”. In it, run the command “chkdsk [drive letter]: /f /r” for each partition.

Experienced users can determine HDD status by the sound of his work. If it starts clicking or whistling, the equipment is most likely faulty and needs to be replaced. Be vigilant, often if hard drive started to “crumble”, it will soon fail, and it is very difficult to recover data from such a device. Also, if the computer freezes tightly after turning on, there is a high probability of wear on the hard drive.

Incorrect BIOS setting

If the computer freezes dead after turning on, very often the reason for this behavior of the system is incorrect setting BIOS. Someone may think that an ordinary user shouldn’t even try to fix something and should contact a professional. But still the computer freezes tightly - what to do if there is no way to call a specialist?

If you approach BIOS configuration with care, even a beginner can handle this procedure. Learn complete information about your computer, and especially about the motherboard. Usually such data is easily found on the manufacturer’s official website. Find out which parameters are most important and what they are responsible for. When working with the utility BIOS settings Never change many parameters at once. First change a few, reboot, check the computer. Only then continue editing. A special mention should be made of the item that is in every BIOS - “Load Fail-Safe Defaults”. It brings all parameters to optimal - in the opinion of the developer.

Sometimes you can download and install a new one on the motherboard manufacturer’s website BIOS version. Never refuse such a procedure. Updates often fix critical bugs and improve stability. It is likely that after installation new version Freezes will disappear. The main thing is to read the instructions in advance.

windows services

The operating system runs a large number of services all the time, either enabled by default or added during operation. The system can work fine without most of them. If some service does not respond or takes up too much processor time, the computer freezes.

To see which of them are in the system and which are running, open the administration window ("Start" - "Control Panel" - "Administrative Tools") and double-click the "Services" shortcut. To get comprehensive information about a particular service, double-click on its name.

First of all, pay attention to those that start automatically. The loading method is indicated in the “Startup type” column. There is only one editing rule - if you do not understand the description, do not disable the component, but find out more about its operation from the Internet. Try to check the stability of the system after each individual manipulation.

Processes and programs

Each program starts its own process (sometimes even more than one) if it is included in endless loop or malfunctions, and the computer does not always freeze completely; Windows 7 still tries to independently cut off oxygen to non-responsive components. It is very easy to identify a frozen element - it usually takes up the lion's share of RAM and almost all the processor time.

Solving the problem using the task manager

You can view the list of running processes in the task manager window. Press the combination “CTRL+ALT+DEL” on your keyboard. If you are sure that some program does not carry a payload, but at the same time takes 90-100% of the processor time, feel free to terminate it (by pressing “DEL” on the keyboard or by calling the context menu). You can also go to the location where the program is stored from here. This will be useful if you do not understand exactly what you are interrupting.

Checking processes is not always the best solution, but this procedure can often help if the computer periodically freezes. Remember that some programs can load the processor one hundred percent during the most active phases of their work. However, a frozen utility will not stop using maximum resources, and one that performs its functions without failures will again go into passive mode after some time. Also, do not try to end the process called System Idleness. It is used to poll other programs and system resources, and the variable in it does not display the processor load, but just the remaining free power.

The computer freezes - constantly, periodically, what to do if it freezes, often

When a computer freezes, it is sometimes quite difficult to find the cause. Resolving this kind of trouble may require quite a lot of time.

After the first such incident, you need to be wary and constantly monitor. It may be possible to establish some connection between some events and the “glitch”. Especially if the PC does not respond to anything.

There are a very large number of reasons why a PC periodically freezes. Often this is where the whole difficulty of finding the cause lies. of this event. Since there are many options why your home PC stopped working normally.

The most common malfunctions associated with this kind of trouble include:

• availability in windows viruses;
• CPU overheating;
• instability of the hard drive;
• incorrect BIOS settings;
• incompatibility of controller and hard drive type;
• functioning or disabled windows OS services;
• there are uncontrolled processes;
• severe HDD fragmentation;
• problems with RAM;
• insufficient volume free space on the HDD where the OS is installed;
• software glitch;
• scanning the OS with a special antivirus;
• presence of malware in startup.

Problem of the 21st century – viruses

Despite constantly updated anti-virus databases, as well as powerful firewalls, various types of malware very often penetrate a PC equipped with the Windows operating system.

Because hackers and just hooligans are designing new Trojans and viruses every day. The presence of such applications in the operating system quite often leads to freezes and glitches.

It often happens that the processor warms up abnormally high temperature. In this case, the PC usually reboots on its own - this is a kind of protection against overheating, it is configured in the BIOS. But it often happens that for some reason it is disabled and does not work. It is in this case that the PC freezes.

BIOS Settings

BIOS is a simple configuration tool, but you need to work with it extremely carefully. Entering incorrect parameters can lead to unpleasant consequences: equipment breakdown, “glitches” and a variety of other troubles.

That is why, if it is necessary to make any changes to it, it is advisable to first consult with a specialist. There is a high probability of PC failure.

Incompatibility of the controller with the type of hard drive

Many users assemble their computer themselves. And this is not always good. Since it is necessary to have certain knowledge about some components. Some of them may simply be incompatible with each other, and therefore there is a high probability of various types of problems occurring. Because of this, the car may simply “freeze.”

windows services

Services operating system greatly affect the operation of the PC. It is always necessary to carefully monitor which of them are currently active. Disabling any vital ones will result in the OS crashing. You should not take any rash actions with services running by default. This will lead to negative consequences.

Presence of uncontrolled processes

Often, all kinds of programs installed on the operating system launch various processes. Moreover, they begin to conduct some kind of independent activity and its products sometimes affect their work extremely negatively. This often happens when installing Kaspersky antivirus or other similar applications. You need to monitor them as closely as possible.

Disk fragmentation

Hard drives that store large files that are subsequently deleted or copied or moved are usually highly fragmented. This leads to a significant drop in the machine’s performance, as well as constant freezing. Dealing with this phenomenon is quite simple; you only need to periodically diagnose the HDD.

Problems with OP

Random access memory (RAM) is one of the most important components of a personal computer. If any malfunctions associated with it occur, there is a high probability of freezing. This may be a consequence of incompatibility between the motherboard and the OP itself; this often happens. It also happens that the bar is simply not inserted tightly enough into the slot.

Small volume of disk C

Sometimes a lot of information is stored on a harddisk: users sometimes fill their HDD to capacity. But you should remember that normal PC operation is possible only if there is about 10% free space. Because otherwise, the data processing process may slow down or even stop altogether, and the machine will freeze.

Software glitch

The market for various programs is currently oversaturated with a variety of applications. They often contain various errors that lead to software failures. This is one of the most common causes of all kinds of PC hangs.

Scanning the system with an antivirus

Very often, the cause of glitches on a PC is viruses. But it is no less rare that malfunctions occur precisely because of antiviruses. Many such utilities are quite complex software packages. This is what can cause the operating system to malfunction. Scanning often results in freezing.

Programs in Autorun

The Windows operating system has a special section that contains applications and utilities that run automatically. Sometimes programs located there cause errors in the operation of the PC. You should carefully monitor the items present there.

Video: 4 ways to fix freezing

A few recommendations on what to do to prevent your computer from freezing

The question is often asked: what should you do to keep your PC in good condition? You just need to follow some of the recommendations outlined below.

Restart your computer

Very often, the problem can be fixed quite simply - you just need to restart your car. Moreover, this operation helps in most cases if there are no serious problems with the hardware.

You can use this method if:

• an antivirus scan was performed;
• any elements were removed from autorun;
• services are disabled.

Disable unnecessary programs

Often you can deal with the problem by simply turning off some unnecessary applications. This can be done through the Windows Task Manager.

This requires:

Afterwards it is advisable to perform a restart.

Check for viruses

Very often, for some reason, many users do not use antiviruses. Having these applications in most cases resolves problems with Restart.

The most functional and powerful today are the following software systems:

Moreover, the use of many antiviruses is free. Their operation and installation require a minimum amount of resources. Removing various types of malicious codes, viruses, and Trojans not only gets rid of glitches, but also speeds up its operation.

Clean off dust

Often the machine begins to freeze if the heating temperature of its individual components reaches critical values. This phenomenon especially often occurs with the central processor.

In most cases, resolving this kind of situation is quite simple - you just need to clean the insides of dust. It happens that overheating occurs due to dried thermal paste - just replace it.

Faulty device

All sorts of problems also occur due to hardware failure. Most often this concerns the following main components:

• hard drive;
• RAM;
• motherboard.

Power supplies, video cards and other components fail a little less often.

Defragment your disk

Highly fragmented areas negatively impact PC performance. This is why it is necessary to periodically perform the defragmentation process.

To do this, you can use both utilities from third-party manufacturers and standard program– it is launched as follows:

Obsolete components

It is very important to upgrade your car in a timely manner. Because operating systems are becoming more and more demanding every day.

If you have problems, you should pay special attention to the following parameters of your PC:

• RAM size;
• frequency central processor;
• speed work hard disk;
• video card performance.

It is advisable to update the car at least once a year. It is necessary to eliminate its weak points - this is the key to stable functioning.

Incompatibility of programs and drivers

Often, all sorts of “brakes” arise due to the banal incompatibility of various utilities and drivers. Coping with this kind of trouble is quite problematic.

The only way out may be to constantly monitor newly installed system elements and remove unwanted ones.

Clean the system

Another opportunity to deal with system freezes can be cleaning using specialized utilities.

The most popular today are the following:

Reinstall the OS

Sometimes even complete cleaning, disk defragmentation, as well as other similar “curing” operations do not prevent the occurrence of “glitches”. Checking the hardware also does not give any results. In this case, the optimal way out of the situation is only new installation operating systems. It might also be worth changing the version.

In order not to deal with the consequences of various kinds of problems, you should simply follow certain procedures to prevent them.

A user monitoring the state of his computer must:

Following all the above tips makes it possible to get rid of many problems associated with your PC. This will significantly simplify the life and work of the average user. What should you do if your computer continues to freeze? In such a situation, it is best to contact a specialist.

You don't have sound on your computer, then this is the place for you.

Turning on Bluetooth on a laptop is easy. Inclusion methods below.

The key to normal operation of a home computer is its timely maintenance and periodic cleaning: both hardware (from dust) and software (from viruses and errors). If the rules and operating conditions are followed, the machine will last a very long period of time without creating any problems. This will make the life of the average user much easier.

Why the computer freezes: reasons and solutions

A modern personal computer is a technology that is often characterized by both hardware failures and software failures.

When the PC responds to user actions with a slowdown, or even stops showing signs of life, this is the reason that it is experiencing problems. This mainly happens when installing new programs, watching videos or working with files downloaded from unreliable sources, as well as when turning the computer on and off or incorrectly resuming sleep mode.

Calling service centers too often will cause damage. family budget. To save money on more pressing needs, you should independently figure out why the machine freezes and does not respond to user actions, and also learn how to solve this problem using standard methods.

Reboot is the last resort

The reset buttons should only be used in extreme cases. When a sudden shutdown occurs, critical errors appear that can lead to irreparable file failures when loading the Windows operating system installed on most home PCs. Therefore, this is not recommended.

To see if the program responds to user actions, you need to launch the Windows task manager using the CTRL, ALT and DEL key combination. When viewed, the dialog box will show all running processes and their status. If the program is “Not responding”, you should use the “End task” button. In the event that this is impossible to do and no measure gives the desired result, you should reboot using the buttons after turning off the PC in the “Start” - “Shutdown” menu. There you can also assign sleep mode. Only if the PC does not respond to this action should you use the “Reset” key.

Let's figure out why a desktop computer freezes and slows down during operation, when turning it on or off, connecting new devices (flash drives, mice, keyboards powered by USB) and how to quickly fix the problem.

Demanding programs

In most cases, the reasons lie in the software itself. Before installing new programs, as well as when connecting new USB devices (flash drives, mice, etc.), it is recommended that you familiarize yourself with technical requirements product: very often users install them on outdated hardware. Due to low windows performance will look for ways to redistribute computing power, slowing down the operation of certain services. The solution to this problem can be to “upgrade” the hardware - do it every few years.

Viruses

The second reason why the computer does not respond to any manipulations, slows down and freezes even when starting and watching a video, is malicious software, popularly known as “viruses”. They can get into the system from various sources: they can be “picked up” on the Internet, when connecting a flash drive or loading a disk, after installing programs from unreliable sources, etc.

The correct solution and prevention of this problem is an antivirus - a program that scans Windows for the presence of such software. In most cases, with a thorough check and elimination of the virus, the system will be cured, however, if it has managed to spread through the root folder, you should think about reinstalling it. High-quality antivirus can protect the OS from the penetration of malware; during scanning, it will monitor every USB device connected to it, as well as every page on the Internet for viruses. It is worth noting that the antivirus itself will offer to do this when connecting a new device. In addition, you can protect your PC in a simple way: do not attach flash drives and others usb devices, and also do not launch a disk that came to you from a dubious source and do not visit suspicious sites while traveling on the Internet.

Extra files

Also, in most cases, the computer slows down due to clutter in the OS. The answer to the question “why?” very simple. During operation, Windows leaves a huge number of unnecessary files that occupy hard drive memory, which in itself affects the stable operation of the system. For example, when watching movies, videos and pictures on the Internet, they are loaded into the browser cache, taking up space in the hard drive memory. A computer freeze can occur when the disk is completely full. A solution to this problem can be the installation of programs and utilities that allow you to clear memory of unnecessary “garbage” without user intervention.

It slows down the operating system and software running in background. Even if the user does not use this program, it still uses RAM to keep things running. To solve this problem you need to do the following: enter the system settings menu, go to the “Startup” tab and uncheck the unnecessary programs that turn on at startup.

Freezes when watching videos on the Internet or from hard drive are the main problem with most outdated computers. To solve this problem, you should upgrade your hardware or reinstall codecs.

The computer also freezes due to an incorrect device driver. In this case, the PC does not respond to manipulations and slows down even at startup. In addition, such an error very often causes blue screen death, even when turning the computer on or off. Before you start looking for a solution to this problem, it’s worth understanding what it is this failure and why it causes the system to freeze.

Blue screen

A blue screen of death is a message about a critical error in Windows.

Blue screens aren't just related to device drivers. In case of any hardware, software or system crash, a blue screen appears before the user’s eyes, on which an error code will be written. In Windows 8, when starting, the blue screen does not report an error, but displays an image with a sad emoticon and a request to reboot. Depending on the cause, the problem that causes the blue screen can be resolved in different ways. If the failure occurs due to device drivers, the PC should be started from under safe mode and use the restore from last point function stable operation system created when logging out. Blue screen due to hardware failures and overheating of the processor, RAM, unstable work The hard drive will disappear only after replacing one of these parts, and the system error leading to the blue screen will be eliminated after reinstalling Windows.

Sleep mode

Quite often, users complain that the computer freezes when loading the system when resuming from sleep mode. Mostly, this problem occurs among laptop and notebook users. The freezing of these devices is explained by the fact that they are connected to a huge number of different USB devices (flash drives, external hard disk, USB mouse, webcam, etc.), which must be CORRECTLY disabled if you want to use the capabilities of sleep mode. If the devices were disconnected incorrectly, after “waking up” the system will try to find them, which will lead to a critical error, and therefore freeze. It is worth making sure that the device was installed correctly when connecting. Another reason why a PC freezes is when it goes into sleep mode while watching a video. To fix this problem, before turning on sleep mode, you need to turn off the video or remove the video disc from the drive.

Updates

Another reason why your computer freezes and slows down is updates. Most background processes during updates (antivirus, Windows Update, etc.) use RAM, which affects the performance of the computer as a whole. Pirate copy of windows, installed on most users' PCs, cannot connect to the update server, causing a system conflict. What can I do to avoid this? Windows Update should be disabled.

Reinstalling windows (which can be done from a flash drive or any other USB source) is one of the most effective solutions for eliminating computer freezes and slowdowns. When releasing a new product, most companies (including Microsoft) often focus on modern PCs, forgetting to optimize their own creations for older generation machines, which is why problems arise when connecting new devices or installing programs and their updates.

If your computer freezes and slows down even when watching a video and you want to fix this problem once and for all, you should pay a little more attention to it: regular cleaning of the system, replacing components, updating some programs and developing a cleaning schedule will help protect it from such problems and make it more reliable!

What to do if the computer freezes and nothing can be done? Turns on only after reboot

Hello friends!

Yesterday a friend asked me to look at the computer and said that there was a problem - it hangs, at first it works, and then suddenly it starts to slow down. If you reboot, it works again for a while, and then the process repeats again. In general, the topic is vast, the reasons are different. But each of us wants to make the computer work quickly and accurately.

Today's article will focus on the most common reasons for this computer behavior. And will be offered universal method solutions that help eliminate other problems along the way.

A small retreat

It's no secret that the vast majority of our readers use the Windows operating system. It just so happens that we have been accustomed to it since the mid-90s. Users of Linux, Unix, and Mac OS criticize Microsoft for being “underdeveloped,” cumbersome, “insufficient,” “inconvenient,” etc. Some of the criticism is fair, of course. But it does not affect the final result - people continued to use Windows and will continue to do so. And if so, then if a problem arises, you need to know how it can be solved without reinstalling Windows and the help of a specialist.

Where can the problem of computer freezing occur?

• windows XP,
• windows Vista,
• windows 7
• windows 10 (still less common than others and slightly different symptoms)

So, you worked and worked and suddenly...

The main symptoms of freezing and unstable operation of a computer or laptop

1. The computer boots quickly, but freezes after a while;
2. The computer boots slowly and slows down more and more during operation;
3. “Hangs” for a long time at boot (immediately after switching on);
4. “Hangs” for a long time when turned off;

It is likely that you have a special case and need help? Write a comment below in detail about what is wrong with you, and we will tell you what to do!

In some cases, errors occur when running programs related to memory; A short reboot helps.

There are two ways: the first way is to look for problems with the hardware, and the second way is to look for problems of the “software” type.

Pay attention! There are many problems associated with a computer or laptop. And this article gives basic recommendations for software only. This is when the computer was working well, but suddenly began to freeze or slow down. And most likely there is no problem in the system unit, namely the software is malfunctioning or viruses have appeared.

But more complex problems often occur. Namely:

I immediately draw the attention of our readers that in this article I will only consider solving problems related to the operation of programs. After all, as mentioned above, it happens that the hardware is also to blame. But most often it’s the other way around. If the hardware fails, you will not be able to fully complete even those points listed in this article. But you have to try to do this - in this way you will carry out diagnostics yourself, and you will already know with confidence who is to blame for the hardware or the programs that do not allow it to work normally.

In most cases, it is enough to simply clean your computer of junk to speed up its operation. That is, there is no need to panic, just watch this recommended video:

The main causes of software glitches that cause freezing

The most common of them:

“The first reason is you, and the second is all your dreams.... The third is all your words, I hardly believed them...”)))

1. Windows was installed by someone on a computer that does not meet the system requirements. A common problem. windowsUltimate (or Maximum) is installed, for example, on an old laptop designed for windowsVista. At the same time, a person wants everything to work quickly and beautifully;
2. Installing so-called “builds” of Windows can also cause such problems over time;
3. Virus infection of the operating system. Occurs regularly;
4. Problems related to state updates of operating system services. The most common (in my practice) problem.

Let's take a closer look at each reason, then it will become clear what to do...

Reason 1. Your computer or laptop is outdated. If the device is old, buy a new one

The solution to the first problem is obvious. If you have old laptop(2007 -2008), and some kind young man installed Windows 7 or (10) Ultimate (Maximum) edition on it, then nothing will help you. You can solve this problem by installing an operating system on your laptop that it can handle. At the same time, its bit depth must be respected. This measure helps, but understandably, for the time being. After all, you want windows that are both faster and more beautiful. And the device is newer))).

Reason 2. Problem with the windows assembly. Correcting service settings

Installation of "assemblies". For our readers who are unfamiliar with the features of installing Windows, I will tell you that in addition to the official Windows releases from Microsoft, there are many unofficial ones. And their sea. They are made by young people, “for themselves.” Those. can be added there according to your taste additional programs, desktop themes; Some important services may be disabled (“they are not needed”). And finding such a “assembly” on the Internet is much easier than the official release.

Such an assembly does not represent anything illegal. If you get it, it’s okay, in most cases you can solve this problem without reinstalling Windows. For the solution to the problem, see paragraph 4;

Reason 3. Infection with viruses. Treating your computer for viruses

Viral infection. Often, when loading, the virus(es) write many processes into the RAM, it becomes full, gradually or not very much; the computer freezes. Here, too, everything is clear, if there is no antivirus - we search, install, check for viruses - reboot. It is better to check using special utilities that are loaded from a disk or flash drive. I recommend the powerful Kaspersky Rescue Disk 10. All information on it is on the Kaspersky website. If helped - problem solved, if it doesn’t help, look at the next point.

Reason 4. Updates are not working properly. Enable/correct services related to computer updates

Problems related to operating system updates and services.

How many of our readers know what a windows update is, what it is needed for, and is it enabled on your device? They know a lot, but don’t specifically include it (“Why, everything works like that!”). I will briefly explain why the update should be included in our difficult times.))) Since 2000, Microsoft has included an update service as part of its operating systems. This was done to improve security and performance. Time has shown that this was the right decision. Over time, the Internet has become filled with active content, the normal operation of which requires additional programs. Simply put, updates, among other things, began to include programs such as Internet Explorer, appeared Microsoft Net Frame Work, Silver Light, and many others. The operation of these programs has a direct impact on performance and is expected to regular update. The updates also began to include updates to versions of computer motherboard drivers and virus definitions.

And for many, update services are disabled during installation, and the user does not even know about it. And we go to the Internet. We install programs. We use websites. As a result, gradually some system files are replaced by others, they do not work correctly and begin to “clog” the computer’s RAM:

There are two ways to fix the freeze - fast and not so fast.

Let's look at the setup using Windows 7 as an example:

Fast way

The fast method is the “fastest” 🙂 it solves the problem in 70% of cases. True, it is very rare - but it may not suit everyone. And yet, this method often eliminates the so-called “error windows updates».

Let's go to the Internet search bar We type: “Download IE for windows 7.” Here's a picture:

Click “download”:

Please note that SP1 (service pack) is required for installation. That's why I pointed out that it's not suitable for everyone. For those who don't have it installed, look below. After downloaded installation file Internet Explorer 11, you need to launch it, installation will take place automatically. The computer needs to be restarted.

Not a very fast way

Start - Control Panel

System and security

Open Windows Update:

Mark as in the picture:

Then click “Check for updates”

The system will check for critical updates, notify you, and prompt you for installation.

You need to respond positively to the terms of the license agreement, install all critical “mandatory” updates, and driver updates for the motherboard. The process is not very fast and may take a couple of days. Accompanied by repeated reboots of the computer. As soon as we rebooted, we start searching for updates again. After critical updates are installed, after checking for updates again, the update service will display the following window:

So today we got acquainted with ways to solve the problem of computer freezing. But... If all of the above methods did not help resolve the problem, then, unfortunately, the equipment is probably faulty, and you need to start checking the hardware. This topic is vast and needs to be covered in another article coming soon. Also, if you are faced with the fact that Windows reports an update error, then this topic will also be discussed in detail in another article.

Good luck to you in solving problems.

That's all for today.

This is the best gratitude. Thank you!

The computer freezes. How to cancel a task

It happens that the computer freezes and does not respond to anything: keystrokes, clicks and mouse movements. The pointer at this moment may not be visible at all, remain motionless or take the form of an hourglass. In such cases, they say that the computer has frozen. Sometimes it is not Windows that freezes, but only a specific program.

If this happens, do not perform any actions, but wait 10–15 minutes. The operating system tries to solve the problem on its own. You are interfering with your actions (indiscriminate manipulations with the keyboard and mouse), giving unnecessary commands to an already overloaded machine (this method of eliminating freezing of a program or the entire Windows on your computer is also suitable for operating systems Windows 7, 8.1, 10).

If waiting is unsuccessful, call Task Manager. To do this, press Ctrl+Shift+Esc or Ctrl+Alt+Del and select Task Manager in the window that opens.

Task Manager - useful system program, with which you can control the operation of applications and view information about them. It allows, for example, to study the list of programs that are currently running (not all running applications are visible on the panel, some operate in the background), stop a frozen program, see how many computer resources a particular application consumes, etc.

When you first launch it, the Task Manager window will display minimal information. To make it appear in an expanded form, click the More details button located in the lower left corner of the window.

The Processes tab of the Task Manager window displays a list of all running applications and processes, for each the amount of resources consumed (processor, RAM, hard drive, Network) is indicated. To find the reason why your computer is freezing, look at which application is using the most resources (pay special attention to the processor and RAM indicators). To make things easier, sort apps by one of the options. For example, to display the process that requires the most RAM first in the list, click the Memory column header.

Find the process that is causing your computer to freeze and context menu execute the command End task. If you find a process that is excessively using PC resources and want to find out what program it belongs to, in the context menu, select the Open file location command.

The task is simplified if you know in advance which program is not responding, just find it and cancel the task.

If the computer still hangs and the described actions do not bring results, press Ctrl+Alt+Del and in the window that opens, execute the Exit command, and then log in again. As a last resort, force restart the PC by pressing the RESET button or holding down the power button on the device for a few seconds.

Problems with computer technology There are many, but some are more relevant than others. One of these is the situation when The computer freezes. What to do in such a situation, how can this problem be resolved so that it does not occur in the future - all methods and methods for eliminating freezes will be described in this article, and they have been tested in practice many times and provide really real answers to these questions.

The freezing problem can be either single or cyclic (the computer freezes from time to time). If your mouse does not move for a long time and no buttons on the keyboard work, in this case it is enough to restart the computer using the reset button on the system unit (in the case of a laptop, you need to hold the power button for 3-4 seconds and turn it on again). If the problem persists, the immediate cause must be identified.

If the user often installs various applications, games, etc., while removing them using the standard “Add or Remove Programs” tool, you need to carefully analyze the registry and clear it of unnecessary entries. It is the oversaturation of the registry that can cause frequent freezes and slowdowns. To do this, you can use the free program CCleaner. After installing and launching this application, go to the registry tab, click on the “Search for problems” button, and then after analysis, click on “Fix”.

This simple procedure will not only solve the freezing problem, but will also improve system performance.

Overheat

This reason is the most common and can be caused by insufficient power of coolers, or an abundant layer of dust on components, which appears during prolonged use of equipment without proper cleaning and replacement of thermal paste. In order to know for sure that this is the problem, just download and install the AIDA64 program. After launching this application, go to the sensors tab and see if certain components exceed the maximum temperature threshold.

If this is the case, clean the system unit yourself, or contact one of the service centers.

Checking the hard drive

The cause of the freeze may be a problem related to bad sectors on the hard drive. To identify such problems, you can use CrystalDiskInfo.

If, after the test, the user displays an alarm on the screen, then the reason is in the hard drive. Try performing deep formatting by deleting all partitions, after saving all important data to another medium. There are also special utilities that help insulate bad sectors However, as experience shows, this procedure will not completely solve this problem. From now on you need to think about purchasing a new hard drive.

But even if CrystalDiskInfo shows that everything is in order with the hard drive, it would not hurt to defragment the disk. This can be done as standard Windows tool, located along the path Start - All Programs - Administrative Tools - Disk Optimization. After launching this tool, you need to perform an analysis, and then click on the “Defragmentation” button.

Also, for these purposes there is a special application Defraggler, which essentially resembles a standard tool, but with larger functionality.

Cleaning startup

To run any program, a certain amount of resources is allocated. At the same time, even if they are idle, a certain amount of memory, etc., is still used specifically for them. If the user has many applications in startup, the computer will take quite a long time to boot, and subsequently the entire system will slow down. In order to fix this problem, you can use the above-mentioned CCleaner application. Click on the “Service” tab and select “Startup”. In the displayed list of programs, place the cursor on the one you want to remove from autorun and click on the “Turn off” button.

You should remove only those programs that the user does not use often. For example, if Skype is not used very often, it is better to remove it from here. After rebooting again, the situation should change for the better.

RAM

With modern operating system and other application requirements for RAM, it has increased. For normal operation, you must have at least 4Gb, and preferably 8Gb of RAM. But if the user has 2Gb and is not able to install an additional stick or buy a new one, you can try to optimize the RAM. To do this:

• right-click on “My Computer” and select “Properties”;

• click on the link " Additional options systems";

• go to the “Advanced” tab and click on “Options”;

• Next, you must also open the “Advanced” tab and click on the “Change” button;

• set the paging file threshold that is recommended by the operating system.

Cleaning a physical disk from unnecessary files and directories

If your computer is clogged with unnecessary files and directories, it also affects the performance of your computer. For quick cleaning, you can use the standard OS utility. Right-click on Drive C: and select the “Properties” line, and then click “Disk Cleanup”.

After the analysis, click on the “Clean up system files” button and the re-analysis will start.

Check all the boxes and click “Ok”, then confirm the operation.

Do not forget that if more than 5% has not formed on drive C: free space, some files and directories located on the desktop, in documents, downloads, etc. you need to copy it to another section, or delete it.

Checking for viruses in the system

Viruses always make unpleasant adjustments to the operation of the system, up to and including completely freezing the computer. Download Dr.Web CureIt and scan your system for malware.

Disabling visual effects

To speed up the OS, if the technology is already outdated, you can disable visual effects. To do this:

• right-click on “My Computer”, select the “Properties” line, then “Advanced system settings”, and then in the “Advanced” tab click the “Settings” button;

• in the window that appears, uncheck the unnecessary effects and click "OK".

Swollen capacitors are the cause of freezing and inability to turn on

If the computer has been used for more than one year, a problem may arise with the capacitors, which after a certain time may swell and not hold the required capacity. Moreover, in this case, the system may not only freeze, but subsequently may not start at all. To understand whether this is the problem, remove the cover on the system unit and visually inspect the capacitors on the motherboard. You also need to view them in the power supply, where they are also located. If the surface has become convex, it is best to take the computer to a service center, where they can be re-soldered for you in a short time.

Reinstalling Windows

After using the OS for a long time, a lot of errors appear in it, a lot of unnecessary files, etc. Therefore, it is always recommended to reinstall the system at intervals of one and a half years.

If you do not have the opportunity to install a full-fledged paid antivirus program in the near future, use a scanner program. The essence of this utility is that it is one-time use, i.e. will scan your computer once and identify threats. You won't be able to delete anything using it. To do this, you can install a trial version of the antivirus.

It is recommended to install more “advanced” programs to protect your computer. For example, Kaspersky gives more guarantees to protect Windows 7 than Nod32. Moreover there is free version Kaspersky from Yandex, which can be used for six months.

Ctrl+Alt+Delete

The key combination Ctrl+Alt+Delete will open the “Task Manager”, where it will be indicated how many programs and processors Windows 7 is currently running simultaneously. In the “Applications” tab, you can, by clicking the “End task” button, disable utilities you do not need - this will significantly increase the speed of work.

In the same window, go to the “Processes” tab and, selecting an unnecessary process, click the “Destroy” button. It will be better if you get help from someone who understands such issues. You yourself risk disabling the process that is responsible for the operation of the system, which will cause a forced reboot.

Internet

Clearing memory

By going to the “Control Panel”, select the “Uninstall programs” section. Next, be guided by the principle of what you really need from what is installed, and what just makes Windows 7 hang.

Every more or less experienced computer user has at least once in their life encountered a so-called freeze, when programs either start working very slowly or stop functioning altogether. At the same time, the computer itself continues to work, and the image from the display does not disappear anywhere. Why this happens is a very difficult question. The reasons for such a malfunction can be very different, as well as ways to correct it. In general, such reasons can be divided into two large groups: hardware and software. In some cases, an ordinary user will be able to get rid of freezing on his own, while in others he will have to turn to qualified specialists for help. Let's try to figure out how best to act in this situation.

The virus completely loads the processor

If your office or home computer suddenly begins to freeze or work slowly, then first you need to ask yourself one very simple question: “Is everything okay with its hardware?” Let's say the computer is new, just from the store, and you have no doubts about its serviceability. In this situation, the list of reasons why it may freeze is significantly reduced. It would also be a good idea to make sure that the operating room is legal. Windows systems- it's no secret that pirated versions, purchased and installed independently, can also present a number of unpleasant surprises. It’s not for nothing that experts often call them “crooked”.

Let us remind you that during normal work with office applications, the computer processor is loaded at most by 1-5%. If the load level constantly remains at 98-99%, this clearly indicates the effect of the virus. Checking the current processor load is very simple - just press the key combination Ctrl + Shift + Esc to open the Windows Task Manager. In the tab Performance you can see a window showing the meaning of this important parameter at the moment (Fig. 1).

Control of running applications

There is another important window in the Windows Task Manager - Memory (Swap file- for other versions of Windows) (see Fig. 1), showing how many megabytes of RAM you are currently using. In principle, if there is not enough RAM on your PC, and you are trying to use many programs at the same time, then this can also cause freezes, but this option is not so common. As a rule, each user already knows what and how much it costs to run on a PC with its parameters, so he is unlikely to cause an “emergency” situation himself. Another thing is if any program starts to launch and work without your knowledge, “eating up” precious RAM, this may well cause problems. In the same Windows Task Manager there are tabs Processes And Applications, where you can try to catch such a “newbie”. You should always keep an eye on the processes and programs that are running on your system, and if your PC begins to run very slowly, the first thing to do is check in the Task Manager to see if there are any new programs there that you did not launch (Figure 2).

However, in case of infection with a virus this option search may not work (viruses are very well camouflaged in the system), so it’s best to use special software- for example, the Dr.Web LiveCD program (based on antivirus scanner Dr.Web). To do this, you will first need to download a 188 MB distribution kit from the site www.freedrweb.com/livecd/?lng=ru, create a special boot disk with it, and then scan hard antivirus disk of your PC. It is very important to use just such an antivirus with offline downloading, since normal startup and operation of Windows if there is a virus in the system is usually no longer possible. Starting the antivirus from removable media- the only option to neutralize the code that interferes with the normal operation of the system. After finding and removing the virus in this way, the freezes usually stop.

Rice. 2

Insidious overheating

The second common cause of freezes is hardware - for example, a damaged power supply or computer cooling system. If the antivirus package did not detect any hidden pests, then you should pay attention to this possible reason. It is noteworthy that the malfunction of the power supply can also be hidden. The computer will turn on as usual, work for a while, but then suddenly all processes will stop. It will be very difficult for an amateur to deal with the power supply on his own - he will have to take the PC to a workshop. However one indirect sign, indicating the fault of this particular unit, is available: open the cover of the system unit and carry out an external inspection of the power supply. If there are any smudges or other external defects, the problem is definitely there.

Not everything is simple with the cooling system either. As a rule, several coolers (fans) are installed inside the system unit, which provide cooling for various components - processor, power supply, video card, etc. In powerful machines, their total number can reach 12! Over time, the moving parts of these fans can deteriorate and cooling becomes ineffective. Dust that collects inside the PC case also contributes to this. As a result, a system unit clogged with dust and poorly functioning fans causes overheating of various parts (in particular, the same processor), which leads to constant freezes. The first steps towards solving this problem are an external inspection of the system unit with with the lid removed and thoroughly cleaning it from dust and dirt accumulated inside.

Pay attention to the sounds and vibrations that coolers make during operation. If they are noticeably different from normal mode, then this a clear sign Fan malfunctions and the need to replace them. There are many universal paid and free programs like Everest, Motherboard Monitor and others that allow you to check the current temperature of the processor and other parts. However, it is hardly worth recommending them, since the reason in any case will lie in a malfunction of the cooling system. It is this that must be dealt with first; everything else is indirect signs.

By the way, an insufficient power supply can also lead to overheating of the system. Most often, this power discrepancy occurs when various new components (video card, etc.) are installed on the PC, but the power supply remains the same, not designed for such a power-intensive upgrade. In any case, overheating should be dealt with, since it not only causes various freezes, but also significantly reduces the service life of components and components.

Checking the hard drive

There are two other fairly common hardware problems that could cause incorrect operation computer and applications. The first of them concerns RAM strips (module defects, overheating, etc.). The memory of little-known manufacturers, and what’s more, with a solid service life, may well present various unpleasant surprises, including the blue screen of death, decreased PC speed and periodic freezes. There are many different programs for testing RAM - MemTest (hcidesign.com/memtest), DocMemory (www.docmemory.com), Memtest86 (www.memtest86.com), etc. Some of them allow you to check the quality of RAM modules without starting at all Windows, which is more preferable. In any case, it is desirable for everyone to have such utilities in their collection.

The second common hardware problem that can cause a PC to freeze is hard drive problems. Typically, its lifespan is about 5 years and depends on operating conditions and the reliability of the manufacturer. As it is used, the hard drive may experience many different problems - mechanical, electronic, logical or hardware-software. As a result, the disk access speed drops, the number of bad sectors etc. In the early stages this is little noticeable, but as negative changes increase, the hard drive demonstrates more and more bad job, which is expressed, among other things, in frequent system freezes, decreased speed of opening files, etc.

You can monitor the status of your hard drive using various utilities, such as the free HDD Health program (www.panterasoft.com), which monitors the hard drive and issues an appropriate warning if problems occur.

Saving defragmentation

Among others typical problems, causing a significant slowdown in the computer and its freezing, there are several more. Firstly, there are various file “garbage” that accumulates in the system as it is used. This also includes unnecessary entries in the Windows registry and temporary files of various programs. Naturally, all this dead weight does not help fast work computer. To get rid of it, various special programs, among which we can recommend the free Russian-language application CCleaner (www.piriform.com/ccleaner). With its help, you can clean your hard drive of virtual garbage, including removing unnecessary entries from the system registry (Fig. 3).

Another reason for PC slowdown may be due to the process of data fragmentation that constantly occurs on the hard drive. Various files are constantly added to the hard drive, removed, changed, as a result of which their parts are chaotically distributed between sectors from different areas of the disk. The hard drive heads must constantly move back and forth in search of scattered file fragments, which significantly slows down the system. This problem can be solved using built-in Windows tools, and with the help of other special applications. To use the standard defragmenter from Microsoft, which opens using the Start menu - All Programs - Accessories - System Tools - Disk Defragmenter. There is an important button here - Analyze disk. It allows you to first test the hard drive for the need to perform such an operation, since this process is quite lengthy and can take several hours. You can also configure defragmentation to run on a schedule. In this case, you don’t have to worry about the appearance of a similar problem on your disks - it will be solved relatively quickly and automatically (Fig. 4).

Our advice. For defragmentation to be effective and go as quickly as possible, you should have at least 20-25% free space on the disk. The situation of a hard drive filled to capacity with files should be avoided.

Avoid crooked drivers

Separately, you should consider the situation when the freeze occurred due to incorrect installation drivers or other software that affects the operation of the operating system. Theoretically, Windows provides a rollback system to the system state prior to the installation of such software. To create a restore point, you need to use the Start button to open the Control Panel, select System - System Protection (System Restore - for other versions of Windows) and use the corresponding button (Fig. 5). In theory, if you installed something incorrectly and the computer began to work poorly, you can always return to this “point” by resuscitating the last working state.

Unfortunately, in practice this is not always possible, since Windows itself often starts to work very poorly after installing “crooked” drivers. In this case, the optimal solution is to restore the system from a previously saved archive using an emergency boot disk created, for example, by a program such as Acronis True Image Home (www.acronis.ru) (Fig. 6). Otherwise, you will have to reinstall Windows from scratch and all the programs necessary for operation, too.

Instead of a conclusion

To summarize, perhaps the easiest freezing situation a user can find themselves in is when installing a problematic program. An important nuance: Windows continues to work normally. In this case, an effective solution may be to simply remove the “crooked” software. All other situations require quite a significant amount of time, serious knowledge of Windows, software for diagnostics and testing, BIOS settings (a number of problems can arise because of this) and other points. If the computer components are faulty or incompatible, this issue can hardly be resolved by the user himself and will require the intervention of a qualified specialist.

Be that as it may, the list of the main typical reasons why your computer may freeze, outlined in this article, should always be clearly understood. Then, when such troubles arise, you will immediately understand in which direction to search for a solution to the problem. This will allow you to resolve it as quickly as possible, with the least financial losses.

Often, users reinstall Windows if the computer starts to slow down. This method may be effective, but it requires a lot of time and does not eliminate hardware difficulties. To restore the previous performance, it is necessary to carry out diagnostics and understand the reason why the system freezes. As a rule, the reason is one of the following.

1. High CPU and RAM load

If the system hangs, check the current usage level system resources. It is not necessary to use additional programs for this. A tool that helps you understand your resource consumption is included with Windows. To open it, simultaneously press three buttons on your computer keyboard - “Ctrl + Shift + ESC”. You can also use the combination “Ctrl + Alt + DEL”, and then select “Task Manager”.

In the manager window, click on the second tab - “Performance”. Here are graphs of the current load on the central processor, RAM, hard drives. Switching between sections is done by clicking on their name in the left column. If the load on one or more hardware components is constantly at its limit (the average value is 80-100%), the computer slows down precisely for this reason.

Important! More detailed information for reasons of load on hardware elements, it is available through the resource monitor. It opens from the link at the bottom of the window.

There are two main ways to resolve hangs caused by insufficient system resources. The first is to increase the amount of RAM, replace the processor or hard drive. To replace the HDD you only need new disk suitable size with appropriate interfaces. Before this step, you should make sure that the reason why your PC is slowing down is a hard drive failure. This can be done using the Victoria or MHDD utilities.

Replacing the processor or RAM on a laptop is a more time-consuming and expensive process. As a rule, motherboards for portable devices have high requirements for hardware compatibility. To find out which components are suitable for your computer, go to the manufacturer's website. It is important that quality characteristics new parts differed significantly from the characteristics of old ones. This will allow you to achieve a significant increase in productivity.

The second way to solve such problems is to free up existing hardware resources. You don't need to buy new parts to use it. It will be enough to find the reason why your PC is slowing down and close unnecessary applications running on the computer in the background.

2. Running unnecessary background programs

You can also find out which applications are currently running in Windows in the “Task Manager”. Go to the first tab - “Processes”. It is most convenient to sort the list by the use of the component that is most loaded. For example, if RAM is often used at 80% or more, click on the heading of the corresponding column. The processes will be listed starting with those that consume the most memory.

If you need more detailed information about processes, add additional columns to the table. Right-click any column header and select the section you want to add. These can be the columns “Publisher” (program developer) and “Type” ( background process, application, Windows process). To end the program, select “End task” in its context menu. You can also mark a line and then press the “Del” button on your keyboard.

3. Unnecessary applications in Windows startup

If you yourself did not launch the unnecessary processes found in the previous step, the reason for their appearance is automatic download when Windows starts. The further operation of such programs can be unnoticeable, since they are minimized to the tray or run in the background. But utilities consume their share of system resources even in such cases. This can cause the device to freeze, the PC to slow down or even reboot.

Autorun of some utilities is enabled immediately after installation. You can check the current startup list on the fourth tab of the task manager. By default, the following columns are enabled in the table:

• Name — program name;
• Publisher - the name of the company that developed the application;
• Status - current status of automatic start;
• Impact on startup - load on the system, causing it to freeze every time it starts.

Advice! To disable the automatic launch of an application when the operating system boots, right-click on its name and select “Disable”.

4. Infecting your computer with viruses

Cause of freezing and slow Windows operation May be viral activity. A number of viruses perform tasks of indexing or encrypting data on the hard drive, as a result of which the PC slows down. Other unwanted applications load the network by sending information over the Internet. A computer freezing in this case is not as critical as the main losses from the virus.

To avoid infection, do not open suspicious files sent to you strangers. Install utilities only from trusted sources - official websites and the Windows Store. Use antivirus programs With active protection. They scan your computer in real time and prevent malicious software from executing. program code. Examples of such antiviruses:

• ESET NOD32;
• Avast;
• Kaspersky Anti-Virus;
• Dr.Web;
• AVG Internet Security.

If you experience regular freezes and suspect an infection, check Windows using a full scan. Scanning all files takes considerable time, however, only this will identify all real and potential security threats. If the antivirus detects files containing a potential threat, send them for online scanning through the VirusTotal service. She will help you check specific file several antivirus utilities at once for more precise definition malicious code.

5. Overheating when the computer is running

Freezing or interruptions in the operation of the device may be caused by overheating. If the system gets too hot, it may slow down or turn off automatically. Shutting down occurs to avoid damage to computer parts, so the problem of overheating should not be ignored. Check current temperature system components possible using the following programs:

• Speccy;
• HWMonitor;
• AIDA;
• SpeedFan;
• Open Hardware Monitor;
• OCCT.

Overheating is most often caused by poor ventilation of the internal components of the device. Fans used to cool parts become contaminated with dust and small particles. As a result, the efficiency of their further operation decreases, since cold air is not able to freely pass through the layer of contamination on the blades. Dust can also settle on radiators and the boards themselves.
