Computer RAM (or RAM) is one of the most important components of a computer. OP is a memory for the temporary storage of information about running programs, services or processes. With the help of RAM communication is carried out between the CPU and hard drives, as well as any external devices. Before the program will be executed, it is necessary that its files get into the processor. This is exactly what OP is doing. In this regard, a considerable part of serious errors and malfunctions arises precisely because of the incorrect operation of the operational memory of the PC. But before you fix any problem, you need to make sure that the whole thing is in RAM. In this article we will understand how to check the computer's operative memory for operability. Let's get started. Go!

Errors in the OP can cause a variety of problems on the computer. For example:

• The regular appearance of the "Blue Screen";
• Constant crashes and hangs in games (including the “unarc.dll” error);
• Bad (distorted) picture on the monitor;
• The PC fails to boot, the download is accompanied by a squeak.

Of course, if one of these "symptoms" is your case, this does not mean that there is a hundred percent problem in RAM. It says only that the cause of the problem may be due to the RAM as well. Therefore, be sure to first perform a check, and only then (if necessary) take corrective measures. In the Windows operating system there is a built-in utility with the help of which you will be able to carry out an audit of the computer's PC It is called the Memory Diagnistics Tool. To go to the program, use the key combination Win + R. Once in the Run window, type (without quotes) “mdsched”. After that, you will see a message asking you to restart the PC in order to run the scan. Clicking "Reboot and check (recommended)", you start the scan procedure.

While scanning is in progress, you can change its parameters by pressing F1. For example, the type of scan, whether to use the cache, as well as the number of repetitions of the test. When the scan is complete, the system will reboot. You can see the test results after logging in.

If for some reason you are not satisfied with the built-in Windows utility, you can use third-party programs. One of these is a great utility memtest86 +. You can download it for free, so feel free to download directly from the official product site. Works memtest86 + as follows. First you need to unpack the archive with the image and create a bootable USB flash drive. Then go to the BIOS and select the boot priority — USB drives. Insert the USB flash drive with the program and boot from it. Scanning will start automatically. Please note that it is best to test the RAM one module at a time, removing or installing them one by one. So it will be easiest to identify the problem module that needs to be replaced. Of course, this method will be acceptable only for advanced users who already have experience in disassembling computers.

If any check reveals RAM errors, the most correct solution would be to replace the failed module or all at once.
