Hi guys, I have a question for all the G5 techs out there. I have a 2.3Ghz DP G5 (8 dimm slots) that I am eager to get running. It's not booting now, and it does NOTHING when I press the power button. (w/ both processors removed). In my other G5, when I plug in the external power cord it makes a very small "thunk" noise that I have heard before in these G5's; I think I have heard that the noise is a sign that the power supply is healthy. However, this G5 does not produce any noise at all when this machine is plugged in. I would be ready to pronounce the power supply dead, BUT, the main 24 pin connector to the mobo produces exactly a 5V power trickle. So now I'm scratching my head... I have no processors installed, but I should at least see the light on the front flash, or the inside red lights flash. I know the 2GB of RAM I have in the machine are good. Is it possible the motherboard is "grounded" or "not grounded" or something? I have heard of that type of thing before but not sure exactly what it means or how to trouble-shoot it. Any other thoughts or suggestions? (I have of course reset the PMU ). Thanks!!
