A couple of months ago I assembled a new build with a lot of relatively new hardware. The basic stats are e6600 c2d, 680i mobo, 4gigs Buffalo firestix, 8800 gts vid card. The computer ran fine for the first month or so, but when I moved to a new city and booted it up, my windows install had been corrupted somehow. I ran the Drive Fitness Test on all the harddrives with no bad results, so I decided to just reformat and reinstall windows. The reformat went fine but when it started to copy the windows files to the hard drive it took a ridiculously long time (hours). And when I restarted and began the installation that took hours and hours as well. It finished installing finally but when I tried to boot it was going so slow that I just reset it. I'm running memtest now but even that seems to be running slow or something.

Sorry for the long paragraph, but I figured I should explain the problem in at least some detail. There's also been another problem, although I don't know if it's related. My BIOS settings were reset to default (I can't remember if I did this myself or if it did it automatically), but when I try to go in and change my memory timings/fsb settings, the bios freezes as soon as I take it off of the "auto" setting.

I'm generally pretty good at fixing my own computer problems, but I've honestly never encountered this problem before. Any help would be greatly appreciated. I'm assuming it's a hardware failure of some sort, but I don't know.
