Or it could be that something was not getting reset properly when the system powered up. I remember problems when the AMD K7 chips came out where some supplies had problem with the startup load, and the system would not boot properly. (I have one here - it boots fine from a 250W K7/P4 rated supply, but will not boot properly from a 450W supply that is not rated for the newer processors.) In any case, I am glad to hear you found the problem. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
