What to do if there is a blue screen. What to do if a blue screen appears or your computer automatically restarts

o Viruses, The cause of a blue screen is quite rare.

Of course, to solve the blue screen problem on our computer, it is very good to first find out the reason for its appearance. To do this, the operating system displays the relevant information to us on a blue screen, which is basically the same, except for two small items - the name of the error and the error code.
How to decipher a blue screen error. Let's look at two cases you may have.

· A blue screen appears when the computer boots and remains on the screen for a long time, giving us the opportunity to read the name and error code.

· A blue screen appears when the computer boots for a second and disappears, and the computer then reboots again, so you and I don’t have time to read anything (more on this complex option below).

You cannot rely on deciphering error codes alone to solve the blue screen problem. The same error, for example 0x0000008E, can indicate a faulty RAM and at the same time infection with a rootkit, and another error 0x0000000A IRQL_NOT_LESS_OR_EQUAL can indicate dozens of reasons. But you shouldn’t reinstall Windows right away if a blue screen occurs, you still need to try to figure out what’s wrong...

In order to ensure that in the event of a critical error your computer does not constantly reboot and you can read the error code on a blue screen, the first thing you need to try is to press the F-8 key on the keyboard when you turn on the computer and get to the menu Additional options boot, then select Disable automatic reboot when system failure,

If it doesn’t help, then it would be useful for you to know this information. I want to say that the operating system is able to save information about the blue screen error in special file, which is called a memory dump, it will be located in the C:\Windows\Minidump folder. But for this you need to enable debugging recording Windows information. Do it right now.

On Windows XP:
Right-click My Computer, then Properties->Advanced->Startup and Recovery Options->System Failure->Turn off the Automatically restart option. Select Small memory dump (64 KB) and click OK.

.

We select the memory dump with the left mouse in the upper window of our program and immediately look at the lower window, information about the error will certainly appear there. By the way, if you press F-8 while the program is running, our blue screen will appear in the lower window.

Microsoft has its own debugging tool, but I would say the BlueScreenView utility works simpler, and the result is no worse.
You may ask, our computer won’t boot, how can we reinstall the audio drivers? Firstly, you need to try to roll back a certain period of time using system restore points, this can be done in safe mode or in the recovery menu Windows problems 7 (when loading F-8) or from the recovery disk of the seven. To remove the problematic driver, in case of a blue screen, you can try to log into safe mode with command line support and type the command devmgmt.msc and you will be taken to the device manager.

After removing the problematic driver, you need to install updated versions drivers, preferably taken from the official websites of device manufacturers. Or vice versa, install an old and stable driver.

Now let's move on to a more complex issue. What to do if a blue screen appears for a second and it is not possible to read the name and error code?

I booted from a simple Live CD and the same thing happened there, there was no drive (C:).
Loading into Acronis program Disk Director 11, my drive (C:) is visible and the data on it is all intact, but nothing can be done with it, during any operation with the partition, Acronis immediately gives the error The file system is damaged!

A utility available in Windows 8 or 7 for hard checks disk CHKDSK, immediately discovered a problematic disk with a broken file system and began checking it for errors in five stages: checking files, checking indexes, checking security descriptors, checking data in files and checking free space!
I had to wait three hours, then I rebooted and my system booted safely, and the missing partition of the connected hard drive also became accessible. In general, friends, this is the first sign that the hard drive will soon become unusable and needs to be checked special programs , for bad sectors and Bad blocks (failed or bad sectors). If everything is more or less successful, in order to use such a hard drive, ideally completely format it and reinstall the operating system on it.

Friends, when your operating system does not boot due to errors on the hard drive, then check Chkdsk utility it is not necessary to remove it, you can boot the computer from installation disk Windows 7 or recovery disk, then enter the recovery environment, select command line, then enter the command:
chkdsk c: / f, which means run a check of the system disk (C:) with the parameters /f - checks for file system errors on the disk and corrects them. Details in our article: Chkdsk program.

Another example: one of mine old friend, I spent a long time looking for the cause of the blue screen on one computer. A newly installed operating system, with native drivers installed on all devices, after 5-10 minutes of operation of any active application(for example, games), went to a blue screen with the Stop error: 0x00000019. Tests were carried out on almost all components, including the Mem test program; the 512 MB RAM was successfully tested, which ultimately turned out to be the culprit. The fact is that on a computer with a relatively weak configuration, there was a powerful gig video card, and only 512 MB of RAM. He replaced the 512 MB RAM stick with a 1 GB one and the blue screen stopped appearing, but the old RAM stick still works on another computer with an integrated video card.

· My friends bought a computer, two years passed and they periodically began to experience a blue screen when playing games. We decided to reinstall the system. We reinstalled and started installing drivers on all devices; when installing the driver on the video card, the system went into a blue screen. Updating the driver on the official website did not help, the problem was solved only by replacing the video card. By the way, on another computer, this video card behaved the same way.
· Exactly the same case happened with a network card installed as an expansion card in the PCI slot. We went through all possible and impossible drivers during installation Windows drivers 8 showed a blue screen with an error and immediately went into reboot, preventing the name and error code from being read. Network card Replaced it and everything started working fine.

· Sometimes people spend a long time looking for the cause of the blue screen, reinstalling the system and drivers, but the problem is simply overheating of the processor; once you remove the side wall of the system unit, look at the dust cap on the processor cooler, and everything will become clear.

· Overclocking the processor, also often the cause of a blue screen, can be treated by resetting the BIOS settings.

· Once, friends, they really asked me to save the Windows 8 system from a blue screen, they didn’t limit me in time, they gave me the whole day. It was not possible to find out the error code; the operating system kept rebooting. First of all, just in case, I made a backup of the faulty system, namely the system partition-drive (C:). If I can’t fix the problem, I’ll deploy a backup and give the computer back without changes, maybe someone else can do it.

I tried almost everything that can be done in this case, the last thing I tried was this method - I replaced all the registry files SAM, SEKURITY, SOFTWARE, DEFAULT, SYSTEM from the C:\Windows\System32\config folder with the same files from the C folder :\Windows\System32\config\RegBack, in it every 10 days the Task Scheduler creates backup copy registry keys - even if you have System Restore disabled and Windows 8 boots safely.

Blue screen of death, also known as BSOD and blue screen of death, is Windows’ reaction to critical errors in the computer’s operation. White writing on a blue background suddenly appears on the screen, after which the device usually reboots, freezes, or turns off.

After restarting, the system works fine for some time. But then, if the error is not resolved, the BSOD appears again.

Sometimes this condition is caused by errors in drivers or failure of computer hardware. The reasons may also be a failure system settings, viruses or even installed programs.

What to do if a blue screen of death appears

Special services built into the operating system can help you.

If you have Windows 10, go to Start → Settings (gear) → Update & Security → Troubleshoot. Scroll to the bottom of the list of available services and select Blue Screen. Click “Run the troubleshooter” and follow the system prompts.

If you have more old version OS or the tool mentioned above did not work, open the Windows Control Panel and go to Security and Maintenance Center. In some versions of the OS, this path may look like this: “Control Panel” → “System and Security” → “Action Center”.

Expand the Maintenance tab and see if the solution recommendations appear here Windows problems. If yes, use the suggested tips.

If all else fails, move on to the next step.

The appearance of a blue screen of death can have hundreds of different reasons and each has its own solutions. Having learned cause of BSOD on your computer, you can find the best way fix the problem.

On the screen death of Windows displays the code of the error that caused it. It can appear as a series of numbers and letters (0x0000000F) or a combination of various words written in uppercase and often connected by underscores (SPIN_LOCK_ALREADY_OWNED).

You need to enter the error code in a search engine and find it this way individual instructions for correction. There may even be a special QR code on the blue screen. By scanning it through mobile device, you will be taken to the Microsoft website with interactive assistant to solve the problem.

If the computer restarts immediately after the blue screen appears and you do not have time to write down the error code, disable automatic restart. To do this, right-click on the “This PC” icon and select “Properties” → “Advanced system settings”. In the window that opens, go to the “Advanced” tab, click “Options” and uncheck the “Perform automatic restart” checkbox.

If you don't want to search the necessary instructions and delving into it or the solution found on the Internet does not help, use the methods listed below.

3. Try simple universal measures

These general measures affect many system parameters and help restore its normal operation. They can also fix errors that lead to the blue screen of death.

1. In system settings, go to "Center" Windows updates» and check for updates. If they are available, install them.
2. Check the system using .
3. Update your drivers. You can go to your computer manufacturer's website and download all the drivers for self-installation. But you can also use free services like

The screen of death is caused in Windows 7 by system errors classified as critical. The OS freezes and latest changes usernames are not saved.

The situation is not the most pleasant, but it is often found in computers with the “Seventh” modification of the system.

There is no general algorithm of actions to eliminate this problem, since it depends on the causes that caused it. Below are specific recommendations that should be taken to effectively resolve the situation.

Why does the death screen appear?

All the abundance of reasons causing BSoD, are classified into two large parts:

1. Software;
2. Hardware.

The first includes failures in system services, incorrectly installed software (including those that provide normal functioning hardware - drivers), viral infections PC, software conflict, etc.

The second part of the reasons that cause a blue screen in computers running Windows 7 lies in the hardware. The record holders for popularity are such important PC components as the hard drive and RAM.

Often, after a user installs an additional RAM stick into a PC or due to poor contact in the slot, a blue background with white letters will immediately greet the computer owner. It is also not uncommon for problems with the hard drive to cause critical errors and OS freezes.

The blue screen itself in Windows 7 is of an informational nature. Its text contains recommendations for troubleshooting and notifies the user of the specific error codes that caused it to occur.

That is why you need to carefully study all the inscriptions displayed by the screen of death. By rewriting or remembering the error codes from the bottom of the screen, you can surgically accurately diagnose and quickly get rid of the problem.

Unfortunately, often the user does not have time to familiarize himself with the output report, so this guide begins with a technique for canceling the automatic restart of the PC after an error occurs.

Setting up your computer

If the user did not have time to commit necessary information from the screen, you will need a little PC setup.

After this, once you know the code, you can use it to find an effective “medicine” that can cure your iron friend.

You need to do the following:

It is recommended to study the meaning of the error code on the resource “bsodstop.ru”. For example, “0x0000004e” may appear due to an incorrectly installed driver.

To find out exactly what software caused problems in the system, you should use the BlueScreenView application, which automatic mode identifies files that cause a critical error. The user only needs to install and open the application.

Based on the detected file, you can find out for which equipment you need to reinstall the drivers. From the above figure we can conclude that there are difficulties with the graphics accelerator, since “ati2dvag.dll” is associated with the video card.

In this case, installing the correct software for the video accelerator will allow you to get rid of the screen of death.

After reinstalling the driver, you need to restart the PC. If the problem could not be corrected, then it means that there are other reasons.

Often the error occurs after an update or installation new program, in this case, the optimal way out of the situation is to roll back the OS.

Rollback

A new program or game is also often the culprit of system failures. In order to return the OS to a working state, it is necessary to perform the following sequential steps:

Installing OS updates

Specialists from Microsoft do not stand aside and are making their efforts to troubleshoot problems that cause BSoD.

They continue to support the now outdated “Seven” and release upgrades that include “fixes” that correct system errors that cause blue screens.

To update you will need to do the following:

The next most popular cause of problems is a simple lack of memory in system partition hard drive. Checking this version will not take much time.

Low memory

On official resource Windows developer 7 it says that it requires at least 100 Mb to function free space on the system volume, however, practical experience has proven that for normal operation"Seven" is required to keep a fifth of the system volume free.

To make sure there is enough space in the partition, you just need to open “Computer” in Explorer.

Having made sure that there is enough space for the OS to function, you should move on to analyzing the availability system errors via the event log.

Event log analysis

To do this, you need to take the following steps:

Antivirus and viruses

Often, simply disabling the antivirus program will resolve the problem. If, after deactivating the security application, the blue screen no longer appears, you will need to complete removal antivirus.

Malicious utilities also cause critical errors, and regular scanning of your PC for their presence is required. Many antivirus software developers have versions of programs that operate from removable media.

For example, "AVZ". By recording the application onto a CD or flash drive, you can treat your PC from malicious utilities.

BIOS

Incorrectly entered parameters in the BIOS also often cause crashes. You can correct the situation by resetting the BIOS settings to the initial state - “default”.

Equipment

A simple inspection of the wear of the cables and the correctness of their connection sometimes allows you to quickly identify the cause of the failure.

If the user has the appropriate experience, it is necessary to open the system unit (SU) and check the connections of all computer components.

For example, when, based on a careful review of the information displayed on the blue screen itself, it is determined that there is no access to RAM, you will need to do the following:

1. Turn off PC;
2. De-energize the computer by disconnecting it from the power source;
3. Remove the SB cover and disconnect the RAM boards;
4. Wipe the contacts with a dry cloth and insert the equipment into place;
5. Start PC;
6. Make sure the problem is resolved.

Similar measures can be taken with other PC components, for example, with a hard drive and sound and video cards. If there is no positive result, then this component may fail and will need to be replaced with a new one.

Hardware diagnostics can be performed using special utilities. For example, “Windows Memory Diagnostic” allows you to identify problems with RAM.

The application records the image boot disk. This ISO must be cut into a CD and booted into the PC from it. The program will carry out testing in cyclic mode.

Good afternoon.

Although, he’s probably not that kind, since you’re reading this article... In general, the blue screen of death is not a pleasant pleasure, especially if you spent two hours creating a document, but autosave was turned off and you didn’t have time to save anything... Here you can turn gray if it’s a coursework and you have to hand it in the next day. In this article I want to talk about step-by-step recovery computer operation if you are tormented by a blue screen with enviable regularity...

And so, let's go...

Probably, you need to start with the fact that if you see a “blue screen”, this means Windows has completed its work with a critical error, i.e. There was a very serious failure. Sometimes it is quite difficult to get rid of it, and only reinstalling Windows and drivers. But first, let's try to do without it!

Eliminating the blue screen of death

1) Setting up your computer so it doesn’t reboot during a blue screen.

By default, Windows OS, after a blue screen appears, goes to reboot automatically without asking you. There is not always enough time to record an error. Therefore, the first thing we will do is to prevent Windows from rebooting automatically. Below we will show how to do this in Windows 7, 8.

Open the computer control panel and go to the "System and Security" section.

Here we are interested in the boot and recovery options.

In the center of the window, under the “system failure” heading, there is an option “perform automatic reboot”. Uncheck this box so that the system does not reboot and gives you the opportunity to take a photo or write down the error number on paper.

2) The error code is the key to solving the error

A blue screen of death has appeared in front of you (by the way, in English it is called BSOD). You need to write down the error code.

Where is he? The screenshot below shows the line that will help determine the cause. In my case, the error is like "0x0000004e". I write it down on a piece of paper and go look for it...

I suggest using the website http://bsodstop.ru/ - all the most common error codes are here. By the way, mine was found too. To solve it, they recommend that I identify the faulty driver and replace it. The wish, of course, is good, but there are no recommendations on how to do it (we'll look at it below)... This way you can find out the reason, or at least get very close to it.

3) How can I find out the driver that caused the blue screen?

In order to determine which driver caused the failure, you will need the BlueScreenView utility.

It's quite simple to use. After launch, it will automatically find and show errors that were recorded by the system and reflected in the dump.

Below is a screenshot of the program in action. Errors when a blue screen occurred, date and time are shown at the top. Select the desired date and see not only the error code on the right, but also the name of the file that caused the error is shown at the bottom!

In this screenshot, the file "ati2dvag.dll" somehow did not suit Windows. Most likely you need to install newer or older drivers on the video card and the error will disappear by itself.

Similarly, step by step, you will be able to identify the error code and file that is causing the crash. And then you can try to replace the drivers on your own and return the system to its previous stable operation.

What to do if nothing helps?

1. The first thing we try to do when a blue screen appears is to press some keys on the keyboard (at least that’s what the computer itself recommends). 99% that nothing will work out for you and you will have to press the reset button. Well, if there is nothing else left, click...

2. I recommend testing the entire computer and RAM in particular. Very often a blue screen occurs because of it. By the way, wipe its contacts with a regular eraser, blow off dust from the system unit, and clean everything. Perhaps due to poor contact of the RAM connectors with the slot where it is inserted and a failure occurred. Very often this procedure helps.

3. Pay attention to when the blue screen appears. If you see it once every six months or a year, does it make sense to look for reasons? If, however, he began to appear after each Windows boot- pay attention to the drivers, especially those you recently updated. Most often, problems arise due to video card drivers. Be sure to update them, or install more stable version, if this took place.

4. If the computer displays a blue screen immediately at the moment Windows boots, and not immediately after it (as in step 2), then most likely the system files of the OS itself have been corrupted. To restore, you can even use standard utilities restoring the system using checkpoints.

5. Try to go into safe mode - perhaps from there you will be able to remove the faulty driver and restore the system to functionality. After this, the best option will try to restore the Windows system using the boot disk from which you installed it. To do this, start the installation, and during it select not “install”, but “restore” or “update” (depending on the OS version, the wording will be different).

6. By the way, I personally noted that in newer operating systems blue screens occur much less often. If your PC meets the specifications for installing Windows 7, 8 on it, install it. I think there will be fewer mistakes overall.

7. If none of the previously suggested solutions helped you, I’m afraid that only reinstalling the system will improve the situation (and then only if there are no hardware problems). Before this operation, you can copy all the necessary data to flash drives (booting using a Live CD, not from your hard drive) and calmly reinstall Windows.

When loading or operating the operating room Windows systems An error or glitch may occur that will result in a blue screen with white text.

Moreover, in this case, you can only reboot the computer, since other actions will be unavailable. It is for this reason that this very screen is called the “blue screen of death” (BSOD).

What is it

The Blue Screen of Death indicates that a crash has occurred. operating system. The reason for such a failure can be very diverse. A similar problem can happen to anyone, so you need to know what to do if a BSOD appears.

There is no need to worry or fuss too much. It is recommended to reboot the system unit; in this case, all unsaved data will be lost.

Often, when you reboot, the problem disappears, but it is still useful to know the reason why the failure occurs. To do this, you need to analyze some line located on the blue screen of death, which contains the error verification string and error verification code, in order to find information on them on the Internet.

System setup

In order to be able to diagnose the problem and fix it if a critical failure occurs in the operating system, you should configure the operating system in a special way.

To do this you need:

• check what's in Windows settings memory dump saving enabled;
• Based on the required size of the memory dump file, you need to check whether it is enough for system disk free space for its location;
• disable rebooting the operating system after a BSOD appears.

Windows XP

To configure Windows operating system settingsXPnecessary:

• enable recording of debugging information, namely go to:

• specify how much debugging information should be written if a failure occurs.

WindowsVista/7

WindowsVista/7 settings are similar Windows settings XP.

Windows 8

In Windows, you can configure settings so that the operating system does not automatically reboot. In Windows 8, this requires:

• right-click on the “Computer” icon and then select “Properties” from the menu that appears;
• in the left menu active window select “Advanced system settings”;
• click on the “Advanced” section;
• in the “Boot and Recovery” field, select “Options...”;

  

• in the “Boot and Recovery” window, uncheck the box next to “Perform automatic reboot”;
• Additionally, you need to change and save the options for saving debugging information. To do this, in the “Write debugging information” window, it is recommended to select the “Small memory dump (256 Kb)” value. It is advisable not to change the directory into which mini dumps will be loaded. The default is C:WINDOWSMinidump.

Transcript of the mixing in Blue Screen of Death

Each critical error is accompanied by detailed description and an eight-digit error code. When you first encounter a BSOD, the information displayed on it seems to be a random sequence of characters, but in fact, the description and error code will go a long way toward identifying what caused the failure and what the error means.



At the top of the monitor is a description of the error, consisting of words cobbled together in capital letters and separated by underscores.

Directly after the error description, some troubleshooting tips are displayed. They are followed by a section technical information with an eight-digit hexadecimal error code.

Depending on the nature of the error, the code is usually supplemented with four auxiliary values ​​enclosed in parentheses.

If the error that caused the BSOD directly depends on a file, its name is displayed in this section.

Reasons for appearance

There are many reasons why the Blue Screen of Death appears.

All reasons for the appearanceBSODin Windows can be broken down into three components:

• equipment;
• drivers;
• programs.

Video: Blue screen in Windows

Equipment

One of the most common reasons which can cause BSOD, in this category are problems with RAM. It needs to be tested.

Failures in the functioning of the data storage system are also common. In this case, it is worth diagnosing hard drive and check if there is free space on it.

Less commonly, the cause of the blue screen of death is problems with the video adapter and processor. It is important to take the test of this equipment using specialized utilities.



In addition to the main components of the computer, problems may arise with additional fees, expanding functionality system unit. You can find out the source of the problem by removing additional nodes and testing the computer for several days without them. If the computer operates normally without failures, then the problem is solved.



You can also try connecting the board to a different slot motherboard. After testing all components separately, you should test the operation of the entire system under load. If it fails under load, the problem probably lies in the operation of the power supply. The way out is to replace the power supply with a more powerful one.

Drivers

There is an opinion that drivers are the source of 70% of BSOD cases. To cure the system, the driver must be reinstalled after removing it. If the problem is not solved, then you need to download the driver from the manufacturer’s website and install it.



There are situations when it is not possible to find fresh driver, in this case you can install an earlier version.

If replacing the driver does not help, then you should check the compatibility of the device with the operating system. If compatibility is not available, it is recommended to replace the hardware or reinstall the operating system.

BY

Problems encountered related to software, are solved similarly. You need to reinstall the existing one, or install the version downloaded from the developer’s website.



The probable cause of a critical error may be the simultaneous installation of two or more antivirus agents per operating system.

Memory dump analysis

To analyze critical memory dumps, you can use one of a huge number of programs, for example, DumpChk, Kanalyze, WinDbg.

Let's look at the example of WinDbg (included in Debugging Tools for Windows) how you can analyze crash memory dumps.



The sequence of actions is as follows:

• download current version programs from the developer's website;
• install the program on your computer;
• run the program;
• go to the menu item “File –> Symbol File Path...”;
• In the “Symbol Search Path” window, click “Browse...”;
• in the window that appears, select the location of the Symbols directory. Then click “OK” twice, and then select the menu “File –> Open Crash Dump...”;
• in the “Open Crash Dump” window, select the path and click “Open”;
• in the “Workspace” window, set the “Don’taskagain” checkbox to “No”;
• The “Command Dump” window will be displayed with dump analysis;
• analyze the memory dump in detail;
• It is especially important to pay attention to the “Bugcheck Analysis” section, which displays possible reason failure;
• to view complete information you need to click on the link “!analyze -v”;
• close the program;
• apply the obtained data to eliminate the cause of the crash.

Troubleshooting blue screen of death errors

The lion's share of blue screen of death errors is due to damage to some system files or lack of or incompatible drivers.

WhenBSODyou need to do the following:




Video: BSOD - Screen

Error codes

To “treat your computer” faster and more effectively, you need to have an idea of ​​what error codes mean and how to fix the blue screen of death problem. Therefore, it is extremely important not to ignore the text that displays the BSOD. Most important information on the blue screen of death is hexadecimal code errors and their description.

Quantity BSOD errors reaches several hundred. It is simply impossible to know or describe all error codes and how to eliminate them. It is much easier and more optimal to use specialized resources that have detailed information about errors, and describes the sequence of actions to solve the problem in the most effective and safe way.



To do this, you just need to go to the appropriate resource, find the error with the required code, study the information about it and restore the operating system in accordance with the recommendations received.

The most common errors:

• 0x00000001 – internal error kernels;
• 0x0000000A – inaccessible memory address;
• 0x0000001E – incorrect processor command;
• 0x00000020 – driver error;
• 0x0000002B – stack overflow;
• 0x00000051 – registry error.

In some cases, the operation of the Windows operating system may end with the appearance of a blue screen of death, which displays a certain sequence of characters.

The appearance of BSOD indicates a critical error in the operation of the operating system. The method for resolving the failure depends on the system error code, which can be viewed at the bottom of the blue screen.
