I say this because dead motherboards, even a motherboard with no CPU or RAM installed will still power on from the keyboard and the power will stay on. So, if your machine is powering back off, I'd say the most likely cause is the power supply. If you have another 9500 power supply or the PS from a 7500 or 8500 or 7200 or 7600 you can test it. Don't hook up all your drives, just try booting up the motherboard and see if it bongs and gives video. If so, it's the PS. If the symptoms remain unchanged, it's probably the power-on circuitry on the motherboard. Jeff Walther -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
