Even the most polished and most secure operating system is by no means guaranteed against failures perceived by the user as errors. Particularly annoying are unknown and unexpectedly occurring errors, sometimes fraught with extremely unpleasant consequences.

It is not difficult to imagine the emotions of a person working on a complex document that is lost as a result of a Windows system crash. To avoid such problems, it is better to prepare for them in advance. And to do this, you need to be aware of how Windows 7 OS is checked for errors. Let us consider separately two serious questions related to the stated topic:

• Checking Windows system files and registry.
• Monitoring the status of your computer's hard drive.

Old-timers of the computer world well remember the utilities of the world-famous Peter Norton, not only the author of excellent books, but also the creator of programs under the “Norton utilities” brand. The first versions of these programs worked even before the advent of Windows - in the then popular MS DOS operating system. These utilities made it possible to detect the presence of errors on the hard drive and identify the presence of other DOS problems. We will be interested in similar tools for Windows.

Files and Registry

Checking OS files can be done in two ways: either using standard Windows tools or using third-party software. The OS has built-in file monitoring tools. To use their capabilities, you need to open a command line window and type the sfc command in it with the /scannow parameter, like this:

As a result, system files will be scanned to detect errors in them. The result will be displayed immediately in the command line window.

The information obtained can be analyzed (at least using the Internet), which can be useful for determining the degree of wear and tear of the OS and equipment. During operation, the program will try to correct all detected violations in system files on the disk.

Additional service, higher scanning quality and reliability of adjustments are provided by third-party software.

For example, the same package “Norton Utilities” (NU) for Windows. Although this tool is the most popular and powerful software package for dealing with OS and computer malfunctions, it still costs a lot of money. Especially in its “professional” configuration. Nowadays, you can find many free analogues of this creation on the Internet.

The Windows registry is the very place where, in addition to the information needed by the OS, a lot of all sorts of rubbish and garbage accumulates. Periodic cleaning of the registry is our direct responsibility. For this purpose, it is worth installing and periodically running the time-tested CCleaner utility (although NU also copes well with this task). Search for it online and download it.

HDD

The appearance of errors in the file structure on a hard drive is caused by wear on the disk surface, failures in Windows disk services (drivers), and positioning errors of the laser subsystem of the hard drive. You can check and disinfect your hard drive using methods similar to the previous ones. We'll look at the easiest way - running the standard disk error checking program that comes with Windows. For this:

• Open the “My Computer” shortcut, select the icon of any of the partitions (for example, “Local Disk C”).
• Open the context menu with the right mouse button.
• Select Properties. A window with tabs will open.
• Go to the "Service" tab
• Click on the “Run check” button.

The program will examine the partition and fix any problems. Perform the same operation with the remaining partitions.

Computer testing: components and programs.

A good computer owner is like a good car owner: he not only uses it for its intended purpose, but also tries to understand at least a little bit what modules are intended for what. You don't need to be a specialist to understand the signs of basic problems that arise during use. And to do this, you can just master testing your computer using functional but easy-to-use programs.

The latest versions of Windows have a number of useful utilities that some people are not aware of or have no idea why they are needed.

Computer testing: and performance

The name speaks for itself. To automatically launch the utility, press Win + R and enter the command

Perfmon /report

The system data collection process will begin immediately. The report will contain a huge amount of information that at first glance will seem purely statistical. The first thing you'll probably be interested in is the Warning tab, which contains errors from the current Windows session. This window duplicates faults, for example, in the device manager, but here, unlike the first one, it gives simple advice on what can be done about this:

On the plus side, there are additional links in each of the points, in which a beginner can get confused, but this does not prevent them from providing a lot of useful information. Thus, the Resource Overview tab contains a color indication of the load on the processor, network adapter and RAM strips. Green – normal, yellow – take a closer look, red – you have problems:

In general, it is useless to describe the utility in full. Run the command and go through the tabs slowly. You will know where to return if something happens...

Computer testing: RAM diagnostics

Did you think that this was the prerogative of servicemen? Now you can do it too. This will not happen in the current session - this is simply impossible - but when you reboot, or the next time you turn on the computer. The utility is located along the path:

Start - Control Panel - Administrative Tools - Windows Memory Checker

The test will start in text Standard mode. The settings can be changed, and at the end of the test, if errors are identified, the system will offer correction options and may even indicate the faulty module.

Testing your computer: Windows Event Log

This log, in a nutshell, will provide an overall picture of the applications being launched in Windows sessions, indicating the exact time the programs started and ended, possible malfunctions and even system failures, indicating their causes. The log will not indicate a faulty module, but conclusions can be drawn. This is where the user goes for a sudden computer shutdown, etc. In fact, this is no longer testing a computer, but its “black box”.

Computer testing: problems with video and audio playback?

The following diagnostic tool has been accompanying us in Windows for a long time. This is a notorious technology invented by Microsoft developers to describe the entire range of tools for working with API(application programming interfaces - application program interface) programs that work with video and sound. So, starting with Windows 98, we are familiar with DirectPlay responsible for sounds, video - DirectShow and graphics - Direct3D.

In general, you can look at the results of Windows checking the installed video and audio settings right now with one command:

Dxdiag.exe

The system will conduct a survey of all devices that are involved in the process of playing video and sound and will display a window with several tabs in which the corresponding summary will be given.

Computer testing: All Windows drivers

Would you like to see them in their entirety? Easily. Open the command console and type the command:

Driverquery

Here you can admire detailed information about those installed on the system. There you can also check the relevance of drivers by installation or update date. However, do not be alarmed if you find dates that are 5-7 years old: your system will have plenty of these drivers for some mastodon devices (for example, a card reader or optical drive), and sometimes the date does not reflect the changes made to it ^

However, it is possible to check which driver is slowing down the system and needs to be updated. To do this, we will have to use a couple of free utilities that can easily detect broken device drivers. I wrote about this in detail in the article. Read at your leisure.

That's all, we'll look at testing a computer from third-party developers another time.
Good luck

). In this case, some begin to worry and look for all sorts of reasons and ways to eliminate freezes.
I will not repeat myself and write why this happens, because... The article is not about this and I have already given a link to solving problems above.
I’d rather show you one interesting way that will help you check your system for errors.

Few people know, but in Windows OS there is one useful “little thing” that can search And correct errors in the system itself. Moreover, it will not touch third-party programs, but will only check its system files. This is useful and interesting because many do not think that the reason may be hidden in the system itself, but feverishly begin, and so on. All in all . Yes, this is useful and can lead to good results, but with all these actions it is good to remember what I will write about below.

I already wrote a little about this function in the article, which can also arise due to a failure in system files, which are often forgotten. But still, within the framework of this article, I will repeat...

So, let's run:

and enter it into sfc /scannow:

The system check will begin:

All you have to do is wait.

For those interested, here is a description of the command and keys.

sfc
Where:
/scannow – immediately scans all protected system files.
/scanonce – scans all protected system files once at the next system boot.
/scanboot – scans all protected system files at every boot
/REVERT – Sets the initial parameters to default.
/ENABLE – Enable normal operation of Windows file protection
/PURGECACHE – Clear file cache and check files immediately
/CACHESIZE=x – Sets the file cache size

In the command line (Start -> Run -> cmd) write the command sfc / and the desired key.

After the check is completed, the system will report the results and ask you to reboot.

That's all I have. Thank you all for your attention.
