This is the 2nd time I have experienced this issue and I am trying to troubleshoot what it is so if anyone can help direct me I would greatly appreciate it. Anyway, recently and once before, my computer started to freeze intermittently (work, freeze for a second, repeat), until it just froze at which point I restarted and I received a disk read error and was unable to boot into xp. It sounded like a hard drive error, but just in case, I turned back all my settings to stock and restarted. Same deal. I then rebooted using my other hard drive with Vista Ultimate and managed to back up all my files on the hard drive that wasn't booting. I reformatted the drive and installed windows xp again and it had worked like a charm. However, yesterday, the same thing occurred and this time resulted in a blue screen after several restarts and running CHKDSK. My other drive with Vista would also not boot. Could this be an overclocking problem? Or is it a hard drive problem? I've been using WD Raptors for a long time and didn't think they would be this troublesome. Anyway, the rest of my specs are in my signature. Thanks in advance for the opinions and advice.
