No display issue

[marcus2704]

Ive been given a PC to see if I can resolve a problem it has whereby when powered on, there is no POST or display whatsoever, just the 'Check Signal Cable' message.

Its got 2 Geforce cards in SLI, there is no onboard graphics unfortunately and I dont have any spare cards. On a side-note, the PC was caked in dust inside, which Ive done my best to clear.

So far Ive tried -

Systematically trying each card individually, each of the DVI outputs.

Tried two seperate monitors

Removing the battery to reset the BIOS

Stripping it down to bare minimum (1 DIMM, no HDDS, no Sound card etc)

Im thinking its a dead mobo, but can anyone suggest anything else I could try?

have you tested the psu to make sure its actually getting power?

Also try it with no memory at all,if you get a beep code then it's a good sign that the motherboard is ok.

As said above,check PSU too.

The only other thing it could be is the CPU itself.
