The Quad fires up, no chime, reporting an intermittent "two flashing beeps" (RAM not detected) and/or red LED "checkstop" error before the fans spin up fully (so loud it nearly sounds like it is about to take off, Harrier-jet style). I've alternated the known working DDR2 RAM to various slots to no avail, CUDA reset etc.
Next step will be to remove the LCS (the original single pump Delphi unit, superficially it looks quite good however - no visible leaking), remove and reseat the processors. I believe I can strip the system down to one processor card to diagnose if a CPU board is faulty. Some troubleshooting should get to bottom to see if the CPU cards, motherboard or LCS is causing all the bother. Worst case scenario is if the motherboard is faulty, it is fairly cheap to replace.
It came with a 7800GT, which will do the job!
