$10 says its your motherboard. I had the exact same thing happen to my system. The SATA chip flipped out, causing a slow cascade of failures that eventually took out my entire system. The SATA chip caused my hard drive to do some crazy power surge or something, which caused the power supply to blip, which made my processor unstable at anything faster than 1400Mhz (its a barton 3200+) and also the RAM unstable at anything faster than 133Mhz (its PC3200).
I replaced the motherboard when everything went to hell, thinking that the new mobo would fix it, but it was already too late. My system is still limping along, but I basically need to replace the entire computer before it'll ever be stable again.
