Hello,
This can be related to the Windows Explorer process, the display driver, or corrupted system files.
Here are the troubleshooting steps you can try first:
1
Run the System File Checker Utility Scan.
Open the Command Prompt (Administrator) window.
Run these commands one by one and click Enter for each command.
Dism /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Once done, restart your computer.
2
If the flashing still occurs,
Go to Start > Settings > System > Recovery > Fix problems using Windows Update > Select "Reinstall now".
This will download the repair version of the existing Operating system on your Windows Updates page.
Once the update is ready to install, install it on your PC and see whether the issue is fixed.
