Ok I have the Asus A7v333 MB with an AMD AThlon XP 2000+ Chip. In the Bios I have it set to 1667(?) for chip speed and everything is jumperless. I am not trying to Overclock the CPU in any way. I am running XP Pro on the machine. It seems like every 3rd or 4th time I power on the machine I get a Failure do to overclocking message and I get dumped into bos screen to set the CPU speed. I set it back to 1667 and save and the system boots fine for the next few times. Any Ideas?
