Mac G5 spontaneously shuts down

I have an older single processor Power Mac G5 (1.6 G I believe) that began shutting down for no reason. It now will not boot - but starts the process normally - with the chime and the fans - but then shuts down after about 15 seconds. I have checked the power supply and am getting 5 volts - I checked the pram battery - and am getting 3.5 volts. I do not see any physical signs of capacitor problems. What am I missing here??

Thanks Machead - the LED diagnostics on the Power Mac G5 don't seem to be of much use - they just indicate to "call apple" if they are red! Any idea what those LED's signify?


Sorry - no I do not have any more information to provide.
