Have you tried a System Restore to a date before the problem started?

If that does not work, try this:

Type cmd in the search box, right click on cmd.exe and select Run as administrator.

At the C:\ prompt, enter sfc /scannow. This will check for corrupt system files and try to repair them.

check your pc cpu temp
and check hdd
