you neglected to say what version of Windows you're running. In general this could most likely be caused by excessive heat or bad sectors on your hard drive. To determine if it's heat, download SpeedFan from here. I would also run CHKDSK and let it check for and attempt repair of bad sectors. Bear in mind that depending on the size of your hard drive, this could take 2 or 3 hours to run.
