As you know, not one of all known modifications of Windows can constantly work in optimal mode. Unexpected malfunctions, errors and malfunctions occur in the system every now and then. Often they can be so critical that the system stops working in an instant or functions with the constant occurrence of emergency situations, causing a spontaneous reboot, blue screens, freezing, restricting access to some features or tools, etc. How to check the system Windows 7 for errors, and then we will talk. The basic methods described below can be applied not only to the seventh modification, since they work without restrictions in all versions.
What errors do you need to correct most often?
Before considering issues related to how to check Windows 7 for errors, let's immediately determine which failures will have to be fixed. Naturally, it will not be possible to describe all possible situations simply physically, so we will dwell on the most common phenomena. Among them, the following problems can be highlighted:
- hard drive errors;
- problems in the work of RAM;
- damage to important system files that ensure its operability (including device drivers).
How to check Windows 7 for errors and fix them: hard disk problems
So, the failures associated with the hard drive can be attributed to the most common. If the problem is precisely the errors of the file system of the hard drive or solid-state drive, you should not use third-party software yet, since in the simplest case you can limit yourself to the means of the OS itself. Everyone knows how to check the Windows 7 system for errors that theoretically may be present on the HDD or SSD.
To do this, in the "Explorer" on the selected disk or partition through the PCM menu, you must call the properties section, and on the service tab, use the test button. It is not necessary to set additional options, as was the case in earlier modifications of the system for automatic correction of found failures. They will be involved anyway.
We’ll talk about testing system or logical partitions separately in the command console, but for now, let's see what can be done if the hard drive is supposedly physically damaged or begins to “crumble”, which can also lead to system crashes.
In such unpleasant situations, you can advise not even special third-party programs designed specifically for checking the disk for errors, but the most powerful HDD Regenerator utility of its kind, which allows you to reanimate the hard drive even if the most critical damage is detected. And this guarantees the safety of both system components and user files or programs.
RAM Testing
RAM can also cause a constant "crash" of Windows, which is usually accompanied by the appearance of blue screens of death. Testing can be done independently by removing the RAM strips from the motherboard slots and restarting the computer. It is possible to determine the failed bar simply by the fact that the PC boots up without disturbances in the normal mode.
But how to check the Windows 7 system for RAM errors precisely by software?
To do this, you can use either the built-in testing tool that will check the RAM at reboot, or (which is much more preferable) the Memetst86 program or its modified version 86+.
How to check Windows 7 for errors through the command line: basic commands
If we talk exclusively about system tools that allow you to identify and fix errors and failures of most known types, command-line tools are considered the most powerful. They can be used both in a running system and when starting from removable media, if Windows does not boot even in safe mode. As an example, let’s look at how to check the “Windows 7 Maximum” system for errors, although the given commands work in absolutely all modifications. A sample list might look like this:
- checking the integrity of system files with the subsequent automatic troubleshooting - SFC tool commands;
- detection of hard drive errors with their correction - CHKDSK tools;
- testing for errors during recovery - DISM tools;
- automatic recovery or overwriting of the bootloader - a BOOTREC tool.
As already understood, these are only the most commonly used tools. The choice of the preferred tool will depend on each specific case and the identified error.
Troubleshooting with other tools
In principle, it is completely optional to use Windows tools to fix some problems. Often, third-party software products are no less (if not more) effective tools.
So, for example, to fix problems with system components, you can use the program DLL Suite (preferably the ninth version).
To identify non-critical problems of a general nature, including the correction of obsolete or incorrect registry entries, optimizer programs (Advanced SystemCare, CCleaner, etc.) are good.
Needless to say, do not forget about anti-virus utilities that neutralize threats in a working but already infected system (Dr. Web CureIt, AdwCleaner, KVRT) or even without loading it at startup from removable media (Kaspersky Recue Disk). In general, for each specific case, finding something suitable will not be difficult.
If the above tools do not suit you, you can use the built-in troubleshooting tool, but unfortunately there is no full guarantee for fixing absolutely all problems. Similarly, Microsoft’s “native” FixIt utility does not completely eliminate possible crashes and malfunctions.
