• A program for complete PC diagnostics. Laptop diagnostic programs

    The fact that errors constantly occur in Windows operating systems, regardless of their version, will not surprise anyone. In almost 99% of cases out of 100, they are associated with information stored on the hard drive. However, not every error is capable of correcting specific failures. Next, we will focus on the most important aspects of eliminating errors, malfunctions and failures in the system.

    Why is a program needed to check your computer for errors?

    As for the reasons for the occurrence of failures, they can be listed for hours. This includes incorrect shutdown of applications or the entire system as a whole, inconsistency of device drivers with the operating system, sudden shutdown nutrition, physical hard damage disk, errors in system files or their absence, virus infection, incomplete or incorrect removal of software components, etc.

    As you can see, there can be quite a lot of reasons, and not every program for checking a computer for errors is designed to provide a comprehensive solution to the problem. No, of course, you can use so-called optimizers, but, as practice shows, it is better to use highly targeted applications. By the way, you shouldn’t disdain your own using Windows, sometimes they help even better than third-party utilities.

    System update

    As you know, any version of Windows OS contains bugs and shortcomings. Sometimes this can lead to system failures or the emergence of security vulnerabilities. That's why Microsoft patches up holes with enviable regularity, releasing new updates.

    By default, in any Windows OS that supports this function, the search and installation of updates is performed automatically (with a constant Internet connection). As a last resort, you can use manual search and installation in the Update Center if the automatic mode is disabled or the connection is made only at a certain time.

    Drivers

    Very often, errors can arise due to hardware conflicts, or rather, inconsistencies between their drivers and the system itself. Therefore, before you use any computer error correction (removal) program, you need to go to the “Device Manager” and view the conflicting devices.

    As a rule, if there are any in the system, they are marked yellow icon with a question mark. In such a situation, you can try installing either devices from own base system, which does not always work, but it is better to use the “native” disk with drivers or special applications automatic search or driver updates that go directly to the official resource of the equipment manufacturer. You can also add that if the system is enabled, some drivers are also updated.

    Antiviruses for Windows

    Viruses are a fairly serious threat to both the operating system and hardware components. The most simple example You can call the situation with a virus developed back in the mid-90s, when, when exposed to the system, it focused the entire brightness of the screen at one point, after which, naturally, the monitor failed.

    Please note, not everyone standard antivirus can determine potential threat“on the fly” even with updated signature databases, because viruses grow by leaps and bounds. Here it is recommended to use portable utilities like Dr. Web CureIt! Or Kaspersky Virus Removal Tool. In this case, it is desirable that the main anti-virus software and the portable application differ in manufacturer.

    Checking hard drive RAM using Windows' own tools

    Now let's talk about the most common situations where errors occur. This is a glitch in work hard disk, because all information is stored on it. Let's say right away that sometimes problems can arise with RAM sticks, but this is more likely a physical rather than a software discrepancy. And today it doesn't exist software method resolve such conflicts. So if someone tells you that there are utilities that eliminate such errors, this is absolute nonsense. A program for analyzing errors on a computer (for RAM) - yes. But certainly not to eliminate them. A striking example is the Memtest86+ utility.

    But let's get back to the errors on the hard drive. As a rule, they occur in system partition, which affects the performance of the operating system. IN logical partitions they can also be contained, but in this case only the applications installed there are subject to failures, although, as a consequence, their incorrect operation or constant crashes can affect the system as a whole.

    To begin with, you should use a standard scan tool, called from the disk or partition properties menu. In this case, it is advisable to use the automatic correction option system errors. But sometimes this approach may not give the desired result.

    In this case it is better to use command line, which introduces the abbreviation chkdsk with the drive letter. This command is unique in that you can add additional parameters to it in the form of a right slash (slash) and the parameter letter. For example, the combination of chkdsk with: /f is similar to a check with automatic failure correction, but it works much more correctly. And there are a lot of such teams in completely different variations.

    Utilities for analyzing and fixing HDD errors

    If the user is not strong in the system part, let's see what can be done if immediate verification is still required hard drive for mistakes. How to check? Yes, it’s very simple - use any available third-party utility.

    Among them are Norton Disc Doctor, CheckDisk, HDD Scan and many others. For the most part, these are fully automated utilities that allow you to check and correct errors on your hard drive in one click.

    But for experienced users there is a more powerful tool - this Victoria program. Of course, it is quite complex, but it is the most powerful of all known utilities, which has no equal in the whole world. Moreover, it works in both Windows and DOS mode. By the way, it is in the second case that it shows the best results.

    Windows 7: checking system files for errors

    Examination system files- the matter is quite problematic. There is no point in doing this manually, especially since not a single user can really say how many and what kind of files should be in the system. In addition, they may be present, but their structure will be damaged. What to do in this case? It's simple. A program to check your computer for errors in the system part is suitable.

    The simplest utility can be called a small free program BUG DOCTOR. It is capable of automatic analysis and correction of minor errors. Alas, she does not know how to restore system files or find replacements for them.

    Since most system files are in the form dynamic libraries with the .dll extension, for complete analysis, search and automatic download damaged or missing components are fine the utility will do called DLL Suite. It is very often used even in cases where Windows performance any version and not only the “seven” falls below the critical limit.

    Applications for working with the system registry

    One of critical roles plays system registry. Incorrect or incorrect keys can both slow down the system and cause collateral failures. Again manual editing- a thankless task even with special knowledge.

    This is where utilities like Registry Optimizer, Vit Registry Fix Professional, etc. come in handy. At the same time, it is worth recommending the utility iObit Uninstaller, which is indirectly related to this issue. It is designed to remove unnecessary applications and has a mode of forced cleaning of the system from residual files and registry entries. As is already clear, this is not a program for checking your computer for errors, but rather a means of preventing their occurrence in the future due to incorrect uninstallation of applications and their components.

    Comprehensive utilities

    As for complex utilities, they contain almost all of the above modules and check the system in automatic mode. But they are mainly suitable only for inexperienced users.

    Today you can count a lot of them. The most outstanding are Advanced System Care, Ashampoo WinOptimizer, CCleaner, AVG PC TuneUp, Glary Utilities, Error Repair Pro, System Mechanic, Rising PC Doctor and many others. Any such program for checking your computer for errors can not only correct them, but also optimize them Windows operation, for example, by disabling unnecessary background services.

    But, as mentioned above, you shouldn’t expect too much from them, but still use narrowly focused utilities, which largely determines the final result.

    Hello.

    When working at a computer, sometimes various kinds of failures and errors occur, and getting to the bottom of the reason for their occurrence without special software is not an easy task! In this help article I want to post best programs for testing and diagnosing PCs, which will help in solving a wide variety of problems.

    By the way, some of the programs can not only restore the computer’s functionality, but also “kill” Windows (you will have to reinstall the OS), or cause the PC to overheat. Therefore, be careful with such utilities (it’s definitely not worth experimenting without knowing what this or that function does).

    CPU testing

    Rice. 1. CPU-Z main window

    A free program for determining all the characteristics of a processor: name, core type and stepping, socket used, support for certain multimedia instructions, cache memory size and parameters. There is a portable version that does not require installation.

    By the way, processors of even the same name can be slightly different: for example, different cores with different steppings. Some information can be found on the processor cover, but usually it is hidden far away in system unit and getting to it is not easy.

    Another important advantage of this utility is its ability to create a text report. In turn, such a report can be useful when solving a wide variety of problems with a PC problem. I recommend having such a utility in your arsenal!

    One of the most frequently used utilities, at least on my computer. Allows you to solve a wide range of problems:

    Control over startup (removing everything unnecessary from startup);

    Monitor the temperature of the processor, hard drive, video card;

    Obtaining summary information on the computer and any of its hardware in particular. This information can be indispensable when searching for drivers for rare hardware:

    Overall, in my humble opinion, this is one of the best system utilities, containing everything you need. By the way, many experienced users are familiar with the predecessor of this program - Everest (by the way, they are very similar).

    One of the best programs for testing the performance of a computer's processor and RAM. The program is based on complex mathematical calculations that can completely and permanently load even the most powerful processor!

    By the way, the program works in all popular Windows operating systems today: XP, 7, 8, 10.

    Temperature monitoring and analysis

    Temperature is one performance indicator that can say a lot about the reliability of a PC. The temperature is usually measured for three PC components: the processor, the hard drive and the video card (they are the ones that most often overheat).

    By the way, the AIDA 64 utility measures the temperature quite well (about it in the article above, I also recommend this link:).

    SpeedFan

    This small utility can not only monitor the temperature of the hard drives and processor, but also help adjust the rotation speed of the coolers. On some PCs they make a lot of noise, thereby irritating the user. Moreover, you can reduce their rotation speed without harm to the computer (it is recommended to adjust the rotation speed experienced users, This operation may cause your PC to overheat!).

    Core Temp

    A small program that measures temperature directly from the processor sensor (bypassing unnecessary ports). The accuracy of the readings is one of the best of its kind!

    Programs for overclocking and monitoring video card performance

    By the way, for those who want to speed up a video card without using third-party utilities (i.e., no overclocking and no risks), I recommend reading the articles on fine-tuning video cards:

    Rice. 6. Riva Tuner

    A once very popular utility for fine-tuning Nvidia video cards. Allows you to overclock an Nvidia video card using standard drivers, and “directly”, working with iron. That is why you should work with it carefully, without going too far with the parameter settings (especially if you have not yet had experience working with such utilities).

    Also, quite well, this utility can help with settings for resolution (locking it, useful in many games), frame rate (not relevant for modern monitors).

    By the way, the program has its own “basic” driver and registry settings for certain work cases (for example, when starting a game, the utility can switch the video card operating mode to the required one).

    Rice. 7. ATITool - main window

    Very interesting program overclocking program ATI video cards and nVIDIA. It has automatic overclocking functions, and also has a special algorithm for “loading” the video card in three-dimensional mode (see Fig. 7, above).

    When testing in three-dimensional mode, you can find out the number of FPS produced by the video card at one or another fine tuning, you can also immediately notice artifacts and defects in the graphics (by the way, this moment means that it is dangerous to overclock the video card further). In general, an indispensable tool when trying to overclock a graphics adapter!

    Recovering information if accidentally deleted or formatted

    Quite a large and extensive topic that deserves a whole separate article (and more than one). On the other hand, it would be wrong not to include it in this article. Therefore, here, in order not to repeat myself and not to increase the size of this article to “huge” sizes, I will only provide links to my other articles on this topic.

    Recovery Word documents -

    Determining a malfunction (primary diagnosis) of a hard drive by sound:

    Huge directory of the most popular programs to restore information:

    Testing RAM

    Also, the topic is quite extensive and cannot be described in a few words. Typically, if there are problems with RAM, the PC behaves as follows: freezes, “ ” appears, spontaneous reboot, etc. For more details, see the link below.

    Analysis and hard testing disk

    Analysis of the occupied space on the hard drive -

    Brakes hard drive, analysis and search for causes -

    Checking hard disk for performance, search for bads -

    Cleaning your hard drive from temporary files and junk -

    That's all for me today. I would be grateful for additions and recommendations on the topic of the article. Good luck with your PC.

    Have you ever encountered such a situation - the computer starts to malfunction or turns off completely? What's the problem? It turns out that you don’t always need to contact a service center. Try using specialized software. The use of programs is useful not only in cases of malfunctions. Let's look at the best programs for identifying computer hardware and when to use them.

    Why do you need such software?

    Have you ever encountered situations where you need to know some PC specifications? And this is not the only reason to use such software. Iron detection software is useful if:

    1. Drivers are updated;
    2. To find out the temperature of the HDD or CPU;
    3. When the system slows down and freezes.

    Sometimes it is necessary to know the hardware model or version. Users do not remember such parameters. They may not be in the documentation. Let's consider what software is needed in such situations.

If you don't like complex software, use the minimalist CPU Thermometer.

    The need to test the performance of a particular computer component arises infrequently. Provided, of course, that you are not doing this professionally. And yet, no, no, and there is a need to check how fast the new one is, to measure against other owners of similar configurations with the “parrots” shown by a freshly installed video card, to be proud of the processor’s performance latest generation. We'll talk about what utilities you might need to test your computer's performance.

    Why testing is needed

    I have already mentioned one of the reasons - to check how much faster the system works with new components, for example, after an upgrade. Or you just got your hands on a device and you don’t mind running benchmarks on it. But sports interest is only one side of the issue.

    Such testing allows, among other things, to seriously load the system, both as a whole and its individual components. This can be useful for identifying the source of problems if the computer is prone to random freezes, reboots, blue screens, etc. This is not just a performance test, but also a stability test.

    This can also help you select the optimal driver that achieves maximum performance; testing allows you to make sure that the cooling system copes with its job. For example, when replacing a processor with a newer and possibly hotter one, the old cooler may no longer cope with the increased load. Of course, the processor will not burn out, but it may start to slow down. Why is this necessary? Is this what the upgrade was for?

    In general, such a check is useful in different situations. And in order to carry it out, you need the appropriate tools. IN in this case– specialized utilities and software packages. Next, I will indicate a list of popular and frequently used means. The list, of course, does not pretend to be complete, and if I missed anything interesting, write in the comments. Let's collect optimal set programs, we’ll make such a “gentleman’s” set of needs for testing computer hardware.

    Test procedure

    Just a few words about how to test a computer. This is not a revelation, but I’ll remind you anyway.

    First, you need to update device drivers (if any). It is highly advisable to get them (drivers) from the websites of equipment manufacturers. Personally, I'm not a fan of using various programs with sets of drivers or automatically monitoring and updating them. Still, the process of what is installed there on your computer should be controlled independently.

    Secondly. The correct power plan should be installed in the system in order to prevent certain devices from stopping, as well as to exclude any restrictions in the processor operating parameters, etc.

    Thirdly. Disable all running background programs so that nothing interferes with the tests. Naturally, you should not use your computer while the verification process is in progress.

    I guess that's all. Well, also be patient and prepare for the fact that you will have to spend some time on all these activities.

    System check

    PCMark 10

    One of the most popular packages for checking the system as a whole. The program is paid. The basic free configuration has limitations and can only perform general testing. The extended version costs $29.99. At the end of the tests, a certain numerical result is displayed that can be compared with other systems; the test results are available on the Internet.
