You could initially try running a Disk file verification process to detect any file indexing errors and automatically attempt repairs.
Assuming you are using Microsoft Windows 10?,
- Right-Click the 'Windows start' icon and select 'Command Prompt (Admin)'
- Click the response 'Yes' and A 'Command Prompt' window will open up
- In the 'Command Prompt' window enter/type the following text using the keyboard:-
"CHKDSK C: /F" (make sure the 'Spaces' are included as shown)
and then press the 'Enter' key
- Type 'Y' and press the 'Enter' key in response to the "Y/N" prompt.
- Now restart your computer and a CHKDSK Disk check process will commence automatically before window starts up.
The CHKDSK process will take a while to complete, so just let it run undisturbed. On completion Windows will startup as normal where you can check to see if the initial problem has been corrected.
Hope that sorts it for you.
