Confirm that display drivers are up-to-date
Right click on the desktop and open the display control panel software & check for updates.
Verify hard drives
- Start Menu > Computer
- Select a hard drive > right click > Properties
- Tools tab > Error-checking > Check now... button
- The drive cannot be in use for the Automatically fix file system errors option to be selected.
- Uncheck that option to get a report. If no errors are found then no action is required. Otherwise, re-run and the system can attempt to fix the errors after a reboot.
Check for corrupt system files
Running a shell as Administrator:
> sfc /scannow
Check for corrupted file system
> chkdsk /r
Check for hanging drivers
With WPA installed, open a shell as Administrator
> xperf -start perf!GeneralProfiles.InBuffer && timeout -1 && xperf -stop perf!GeneralProfiles.InBuffer myTrace.etl
- Hit Enter once to start the command.
- Right after the system stops hanging, press Enter again.
- After some time a log file MyTrace.etl will be produced.
Actually, that command won't work in Powershell. It creates a system trace that won't necessarily be all that easy to interpret.
