Either way, it’s best to take your device to a hardware expert for this process. And you can also have them repair or replace the device if necessary.

Windows Memory Diagnostic Troubleshooter App Stuck

The memory test process is very long. And it usually gets stuck at certain points for hours. This is the usual behavior, so you have to be patient.

However, if the progression stops for more than 10 hours, there are obviously problems. In such cases, perform a hard reset of your PC to get out of the diagnostic screen. Then you can run the diagnostic app in clean mode or try other memory test software.

We also recommend using SFC and DISM to repair any potential system file corruption.

Run Windows Memory Diagnostic in Clean Boot

The diagnostic app may crash due to some third-party processes. You can try running it in Clean Boot mode to avoid such issues. Here’s how:

  1. Walk in msconfig on Run.
  2. Go to the Services tongue.
  3. Check Hide all Microsoft services and click Disable all.
  4. Go to the start tab and click Open task manager.
  5. Here, select each process and click on Disable.

Restart your PC and run Windows Memory Diagnostic.

Use alternative memory diagnostic tools

There are many third-party memory diagnostic tools on the Internet. Most of them are better than the default Windows Memory Diagnostic for testing errors. Some reliable apps are MemTest64, MemTest86+, PassMark MemTest86, etc.

You can use them as alternatives to the Windows memory troubleshooter application.
