type chkdsk /r hit enter...it will tell you it's locked and will run at next reboot. wait 10 seconds or so (i found immediately restarting tends to skip over chkdsk)
type shutdown -r -t 1 hit enter, your machine will now reboot.
If you see "bad sector" during the chkdsk your drive is bad. If you leave it long enough to run this and you are not looking go here:
Once it has completed go back to event viewer> windows logs> application>search>find...(right hand side)search for "chkdsk" and scroll to bottom. Look for "0 KB in bad sectors" if you see anything besides 0KB it's time to replace that drive.

It COULD be bad PSU but of all the machines I've worked on I have yet to see one come in that is steadily failing because of faulty power. It generally just won't start. If it does it won't boot, lights are on but nobody is home.
Just checked the chkdsk from yesterday, it was 0kb in bad sectors.
