Well, I've tried reversing the power on wires, removing the reset wires, removing and replacing the heat sink/fan, and moving the memory to a different slot, and there has been no change. I don't have spare mbs, memory, or PSUs lying around, so I guess I'll go buy a power supply first, and try that. Thanks for the advice, and keep it coming. Jack | ||||||||||||||||||||||
