Hi I have a problem since rebuilding my pc again with another loop for watercooling. I have had it running for a few days, however everytime i try to start the pc up now the motherboard lights flash quickly and we are talking milliseconds then immediately goes off. I have disconnected everything and removed ram still no luck. However once i remove the GPUs it fires up. So, I put the primary card in and it wouldnt start up then removed and put the slave card in (both 8800GTX in SLI) and it fired up. Does this narrow it down to the obvious that it is my GPU before i RMA it? And if so will i get the same card in return if not what should i expect as it needs to be watercooled to take advantage of my expensive watercooled setup. Thanks in advance guys.
