Not a lot to go on, but try......
Creating a new user
Go to
C:\Windows\System32
Find
Cmd.exe
Right click it and choose run as administrator
At the admin command prompt type
net user JohnSmith /add
hit enter
then type
net localgroup administrators JohnSmith /add
hit enter
type
exit
hit enter
Restart and log in as JohnSmith
See if the new user account provides any relief from the problem.
That may suggest that the issue is unique to your user profile and not a more global issue with the system and or critical operating system files.
