I have purchased a mac pro 3,1 advertised as spares/repair as it chimes but no video, so I assumed it just needed a new GPU.
I have tried 3 different GPU's but I still get no video. The RAM is working fine and the only DIAG LEDs that light up are the 2 power ones. So no EFI and no GPU.
What could be wrong?
