PC training program window test. Checking system files for errors What was the inconvenient operating system MS DOS

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.

In recent Windows versions There are 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 short, will allow you to get an overall picture of the applications 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, since Windows 98 we are familiar with DirectPlay responsible for sounds, video - DirectShow and graphics - Direct3D.

In general, look at the test results Windows installed video and sound settings can be done 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 all as a list? Easily. Open the command console and type the command:

Driverquery

Here you can admire detailed information about those installed in 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 drivers devices. 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 occur 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:

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 Windows file protection
/PURGECACHE – Clear file cache and check files immediately
/CACHESIZE=x – Sets the file cache size

IN 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.
