When Windows Memory Diagnostic doesn’t find any faults, use a more advanced tool like Memtest86+, which runs tests on individual memory modules and detects even the smallest of issues. If any problems are found, it’s best to replace the malfunctioning RAM stick!

5. Reinstall Windows

In case nothing else works, the last option is to reinstall Windows. Since there’s a possibility of data loss, I recommend backing up any critical files to an external storage drive.

To reinstall Windows, connect a formatted USB drive to the PC > go to Microsoft’s official website > download the Media Creation Tool > use it to create a bootable USB drive > restart the PC > change the boot order to the bootable flash drive > run the setup and proceed with Windows installation.
