A program to check your computer for errors. Review of the best

That in Windows operating systemsregardless of their version of the constant mistakes, no one is surprised. Practically in 99% of cases out of 100 they are connected with the information stored on the hard drive. However, not every computer error checking program can correct specific failures. Next, we will dwell on the most important aspects of eliminating errors, malfunctions and failures in the system.

Why do I need a program to check the computer for errors?

As for the reasons for the occurrence of failures, they can beto list by hours. Here, and incorrect shutdown of applications or the whole system as a whole, incompatibility of device drivers "operating system", sudden power cuts, physical damage to the hard drive, errors in system files or their absence, virus infection, incomplete or incorrect removal of software components, etc.

As you can see, there can be a lot of reasons, andNot every program for checking the computer for errors is designed for a comprehensive solution to the problem. No, of course, you can use the so-called optimizers, but, as practice shows, it's better to use narrowly-focused applications. By the way, you should not disdain and own Windows tools, sometimes they help even better than third-party utilities.

System Update

As you know, in any version of Windows OSthere are "bugs" and flaws. Sometimes this can lead to system crashes or vulnerabilities in the security system. That's why Microsoft Corporation with an enviable regularity patches holes, releasing new updates.

By default, in any Windows operating system that supportsthis function, the search and installation of updates is done automatically (with a constant connection to the Internet). In an extreme case, in the "Update Center" you can use manual search and installation if automatic mode is disabled or the connection is made only at a certain time.

Drivers

Very often errors can occur because ofconflicts of equipment, rather, inconsistencies of their drivers with the system itself. Therefore, before you can use any program to fix (delete) computer errors, you need to go to "Device Manager" and view the conflicting devices.

As a rule, if they exist in the system, theyare marked with a yellow icon with a question mark. In this situation, you can try to install or update the device drivers from the system's own database, which does not always work, but it's better to use a "native" disk with drivers or special applications for automatic search or driver updates that directly address the official resource of the equipment manufacturer. You can also add that if automatic system update is enabled, some drivers are also updated.

Antivirus for Windows

Viruses are quite a serious threat, asfor the operating system, and for the "iron" components. The simplest example is the situation with a virus developed back in the mid-1990s, when, when exposed to the system, it focused the entire brightness of the screen at one point, after which, of course, the monitor went out of order.

Note that not every regular antivirus canidentify a potential threat "on the fly" even with updated signature databases, because the viruses grow in leaps and bounds. It is recommended to use portable utilities such as Dr. Web CureIt! Or Kaspersky Virus Removal Tool. In this case, it is desirable that the main anti-virus software and portable application differ in the manufacturer.

Checking the RAM of your hard disk with Windows tools

Now let's talk about the most commonerror situations. This is a failure in the hard drive, because all the information is stored on it. Immediately say that sometimes there may be problems with the slats of RAM, but this is more a physical, and not a software mismatch. And today there is no programmatic way to eliminate such conflicts. So if someone tells you that there are utilities that eliminate such errors, this is absolute nonsense. The program for analyzing errors on the computer (for "RAM") - yes. But certainly not to eliminate them. A vivid example is the utility Memtest86 +.

But back to the errors on the hard drive. As a rule, they arise in the system partition, which affects the operability of the operating system. They can also be contained in logical partitions, but in this case only applications installed there are affected by crashes, although, as a result, their incorrect work or permanent crash can affect the system as a whole.

To begin with it is necessary to use standardA validation tool that is called from the disk or partition properties menu. It is desirable to use the parameter of automatic correction of system errors. But sometimes this approach may not give the desired result.

In this case, it is better to use the commanda line in which the abbreviation chkdsk with the disk letter is entered. This command is unique in that additional parameters can be added to it in the form of a right "slash" (slash) and a parameter letter. For example, the combination of chkdsk with: / f is similar to a check with automatic fixing of failures, 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 you still need an immediate hard disk check for errors. How to check? Yes, it's very simple to use any third-party utility available.

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 fix errors on your hard drive in one click.

But for advanced users there is more powerfulthe tool is the Victoria program. Of course, it is quite complex, but the most powerful of all known utilities, which all over the world there are no equal. And it works in Windows mode, in DOS compatibility mode. By the way, it is in the second case that it shows the best results.

Windows 7: check system files for errors

Checking the system files is enoughproblematic. Manually this should not be done, especially since no user really can tell how many and exactly which files should be in the system. In addition, they are present and can, but their structure will be damaged. What to do in this case? It's simple. A program for checking the computer for errors in the system part is suitable.

The simplest utility can be called a smallfree program BUG DOCTOR. It is capable of performing automatic analysis and correcting small errors. Alas, it is not able to restore system files or search for a replacement.

Because most system files are executedin the form of dynamic libraries with the extension .dll, for a complete analysis, search and automatic loading of damaged or missing components, a utility called DLL Suite is perfectly suitable. It is often used even in cases where the working capacity of Windows of any version and not only of the "seven" falls below the critical limit.

Applications for working with the system registry

One of the most important roles is played by the registry. Incorrect or incorrect keys can both slow down the system and cause side crashes. Again, manual editing is ungrateful, even with special knowledge.

Utility such as Registry Optimizer,Vit Registry Fix Professional, etc. Along the way, it is worth advising the iObit Uninstaller utility, which has an indirect relation to this issue. It is designed to remove unnecessary applications and has the mode of forced cleaning of the system from residual files and registry entries. As is already clear, this is not a program for checking the computer for errors, but rather a means of preventing their appearance in the future due to incorrect uninstallation of applications and their components.

Comprehensive utilities

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

Today they can be counted very much. The most outstanding ones 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 to check your computer for errors can not only fix them, but also optimize Windows, for example, disabling unnecessary background services.

But, as mentioned above, there is no point in expecting too much from them, but still using narrowly focused utilities, which largely determines the final result.
