Yesterday I was extremly lucky and picked up a Powermac G5 for about 50 bucks, was told there was no OS on the machine, but was in working order otherwise. To my extreme surprise I was pleasantly surprised when I got it home to find it was the quad core model, however, everything went down hill from there. I attempted to do a simple boot with just a monitor connected (that I know works) as well a wired keyboard. The computer turns on, I get the chime with a red light that breifly shines behind the enclosure and that is it. There is NO video output to the monitor. Logically my next step was to try the other output on the video card, still nothing. I have reseated the RAM, reset the PRAM, reset the SMU, reseated the video card (GeForce 6600), and tried placing the video card in a different PCIe slot. I have another powermac G5 but unfortunately it is PCI-X and thus I cannot test the video card to see if that is the problem or if it is a problem with the logic board in the quad core g5. SO my question for the community: what could be wrong with this machine? Everything else seems to be in working order, I get the chime, I get a fan rev, there is no LED blinking to suggest that the RAM is bad. Any help is oh so greatly appreciated! Thanks in advance!
