I've got a Power Mac G5 Dual 2.0ghz though I'm having some problems with one of the processors. It seems that about 85% of the times I boot the computer Hardware Monitor and About this Mac only shows one processor. There's still a few occasions that when I turn it on both processors are running and operational but most of the time only one is detected. Is this a sign of a bad processor or bad motherboard? Or is it a hardware problem? I've tried reseating the processor about 4 or 5 times now without any difference. The second processor just seems to kick on whenever it feels like it, really. Any help would be appreciated.
