Click START.
Click RUN.
Type this (without quotes) followed by <enter>:

"sfc /scannow"

Then, after this is completed, move on to this:

Click START.
Click RUN.
Type "cmd" (without quotes) and press <enter>.
Type "chkdsk c: /v/r" (without quotes) and press <enter>.
It will say it can't blah blah blah, and ask if you want to schedule...blah
blah blah. Enter a "Y" and press enter.
Reboot.

Please post a follow-up.
