Why does my 2.5GHZ Quad freeze shortly after booting?
Note that this Power Mac G5 (late 2005) freezes before I can boot into the Apple System Diagnostic or immediately after booting into OS 10.4.11. First LED #2 lights up, and then LED #7 lights up and the unit freezes. Video is fine. I have tried a different video card, and different memory with no luck. I have reset the SMU, and I have vacuumed/blown out the inside of the unit thoroughly. Everything appears to be functioning properly, including the Superdrive.
