    Hello.
    I have bought Power Mac G5 without hard drive. When I pressed power button it only turn on fans. It is normal that it nothing on the screen? Monitor not turning on and it's no error codes or something like this. It's no hard drive fault that monitor isn't working?

    Does the G5 chime? If not does it do any error-beep codes?

    EDIT: Seems I didn't read your post all the way lol.
    Try zapping the PRAM or manually removing the CMOS battery and waiting for 5 Mins before putting it back in.(It looks more like a chubby AA then a traditional round clock battery PC's have.).

    I bought 2 PowerMacs G5s.

    The single cpu worked perfectly fine.
    The dual cpu wouldn't boot. Tried swapping out the GPUs and nothing.

    You might have a broken computer.

    Probably motherboard gone bad, I have one which did boot couple days ago and all of sudden only fans start to spin and after a while they ramp up which normal with these machines when there's something wrong.

    No power led, no chime, no red led near processor. Nothing to tell what's wrong.
    I suspect motherboard and spesifically that U3 chip which Apple desgined themselves (as advertised when they introduced PM G5 :) ). That chip runs hot and maybe detach from motherboard... or CPUs burn, power supplies explode, water cooling leak etc.
