Ok, I built this computer last June, 2008. It seemed to work perfectly fine until after 6-8 weeks, it started to bog down alot. It would take 5-10 minutes just to boot up, video files would become slowed down and create an occasional screeching sound, PC games would become almost unplayable, and when checking my CPU performance under the task manager, a simple low res avi file or even a youtube file will cause it to spike up to 20-40% every 20sec or so. When I have nothing running it is usually only around 0-4%.
Well I did find a temporary fix for it. Reinstall my OS. It would then run perfectly fine for another 6 weeks or so, then bam, it starts going sluggish again. I've been doing this every few months but it just seems to get worse. This last time I reinstalled my OS, it only lasted about 4 weeks before it started hittin the brakes again. Is my CPU bad? I've installed Windows on several different hard drives and even tried upgrading to windows xp 64bit and adding 2 more 1gb RAM.
Here are my specs
Asus P5N-D LGA 775 (nforce 750i SLI)
2x EVGA Geforce GT 512mb (SLI)
4x 1gb G.Skill (DDR2)
Intel Core 2 Duo E8400
OCZ 700w PS
and not as important but I'll list em anyways
3x IDE harddrives (Western Dig)
Soundblaster Audigy 2 ZS
PCI IDE controller (since all of my drives are a little older, I needed an extra IDE slot)
