yes i also found that it was the power supply, the atx plug had a prong that was turning black, so i cleaned it up and am putting a new power supply at the top of my things to get list
i have this same problem, it started happening just as soon as i installed my new 6800
at first i thought that it might have needed a fresh os, but it happened during xp setup
anybody else have this problem?
ive got an athlonXP 2200
