About 1 hour ago i was playing counterstrike source and it kept freezing for a few seconds then resuming, every 10 seconds or so, i thought it was just this one time, then it started doing it in windows, i rebooted, BSOD'd over and over, so i reformatted. However it started doing the same again, however seems to have settled down for now, but does anyone have an idea what hardware failure could cause this? Sorry i couldn't get the BSOD code, i was in a hurry.
