26.07.2021 13:02

On Windows 10, memory diagnostics is very easy. This guide will show you how to do it.

When the computer's memory stops working properly, it usually manifests itself as follows:

  • Windows suddenly freezes
  • Bluescreens occur regularly, often with changing error messages

Often, these crashes pile up over time until the computer may be hard to use.

With Windows 10, you can easily check if your computer's memory is working properly. First, press the Windows and r keys together on your keyboard. The following window opens:

Next, enter the command mdsched.exe in the input field:

If you then click OK, the following query appears:

Select Restart Now and Check for Problems. Windows then shuts down and starts the memory test:

Now press the F1 key on your keyboard to open the test settings page:

It is recommended to use the following settings:

  • Test Mix: Extended
  • Cache: On
  • Pass Count: 3

If you have adjusted the settings, the test is restarted by pressing the F10 key. Depending on the selected settings and the size of the main memory, the test run can take several hours.

If errors are found, you can usually see this directly during the test run in the Status area. Otherwise, Windows will tell you at the next startup whether the test found errors or not:

Alternatively, the results are also stored in the system logs and can be viewed there. To open the Event Viewer, press the Windows and r keys and type: eventvwr.msc / s

If you confirm with OK, the program opens. In the left-hand menu, open the folder Windows Logs and under it the System log. Then look in the middle for an event with the source MemoryDiagnostics-Result. If you then click this, you will find the test result below in the information in the General tab:
