Well i just picked up a quicksilver powermac g4 733mhz cheap (20 bucks...lol). Mainly cause it wont power up. It didnt have a cmos battery in it so i put one in and still nothing. Basically what happens is once i hit the power button it lights up while im holding it and then shuts off, the powersupply fan spins up and then shuts off and nothing happens. Any clues? ive tried diffrent ram in it, removed all components... reset the pmu by holding the button on the mobo.
