You say you ran "disk checking" but do you mean you ran the full disk check including the fix "F" switch from a command window? If not then, in a command window, type "chkdsk /f C:" (omit the quote marks but include the spaces) and press Enter. This will take some time to run to completion and at the end it may show corrupt areas of your disk which it will set-aside (it will "fix" them) so that they cannot be used again. If it finds corrupt ares it may be that your HDD is on its way to failing so ensure all your user files are backed-up somewhere safe.
