If you encounter frequent errors on your PC for many programs, sudden system freezes or other problems such as long waits for uploads, it is not Windows's fault, there can be several causes that we have examined in the past talking about how to solve Windows errors when there they are frequent random blocks. If we have already done an antivirus check, when the PC freezes or does not respond regardless of the program in use, it may be that there is a hardware defect related to RAM memory. Fortunately, in Windows 10, Windows 7 and 8, Microsoft has included a program for the control of the RAM memory chip, hidden but very important to know and know how to use also because it is simple and very precise.

To open the RAM check tool in Windows, you must search for Windows Memory Diagnostics from the Start menu. To do this you can open this tool by pressing the Windows R keys together and then typing the mdsched.exe command
After clicking on the program from the Start menu, you activate the program which will begin its work as soon as you restart your computer.
The memory diagnostics tool loads with a very spartan graphic, on a blue screen made of writing, which however must not intimidate anyone.
The test is completely automatic, so you can follow its progress marked with a progress bar and a percentage.
The Windows Memory Diagnostic Tool performs the test repeatedly by writing values into memory and then rereading them to verify that the data has not changed.
By default, the instrument runs with a standard test, but you can also change the type of test.
To change the type of test, press the F1 key on the keyboard to open the Options and choose a basic quick test or try an extended test that lasts eight hours or even longer.
In the program options you can also choose the cache, which however should be left on Default.
To select a different cache option, you have to press the TAB key and then use the up and down arrows to select a different option.
Disabling the cache means forcing the processor to access all data from the memory module.
Pressing TAB again takes you to the third section of the options, where you can choose the number of passes, i.e. the number of repetitions of the test.
2 is the default option and there are no particular reasons for changing it.
The F10 key is used to confirm the options.
At the end of the RAM test, both if errors have been found and if all is well, a message is displayed when the computer is restarted.
If errors were found, a Windows Memory Diagnostic tool window appears.
To see details about the detected error, open the Event Viewer, which is found using the Start menu and writing " events ".
In the Event Viewer window, to find the description of the errors on the RAM, select Windows Logs> System and then under the Source column locate the MemoryDiagnosticsResults row and event ID 1102.
In general, however, if a memory error is detected by the test, the only possible solution is to replace the RAM chip inside the computer.
This operation is quite simple and can be done even without the intervention of a technician.
We saw in another guide article how to change RAM and which RAM to buy.
Unfortunately, Windows memory diagnostics cannot tell us which of the RAM chips is damaged, so if you have multiple banks of RAM inside your computer, you will need to replace one chip at a time and run the test again until you find out which one is broken.
Ram, I remember, is also one of the most common causes for Windows blue screen errors.
If desired, you can also do a RAM memory check with an external program like Memtest86 +, which is highly recommended by computer professionals.
In this, however, the use is a bit more complicated because you must first burn the ISO image of the program on a CD or USB stick and then start when the computer is booted.
Certainly the Windows memory diagnostic tool is much simpler to use.
