I'm in the process of finding stability with my overclock, and my hard drive coud take so many Bsods, and froze during windows boot. So had to perfom an install, it left my old windows in windows.old. Now, its working all fine, but I still am ironing out the Bsods, but what should I do to my hard drive in order to stop it getting to this state again? I was defragging quite a lot before, run chkdsk a after a few bsods?
