I swapped another E6600 and put a 7950GX2 on a P5B Deluxe and I ran Othoros to see how the overclock was. I walked away and when I came back the computer restarted and I smelt something burnt. At first I thought it was my CPU I swapped it with two other and nothing, then tried the ram, and two other video cards. I've cleared the CMOS, taken out the battery and everything and nothing, no video but everything else turns on. I've tried both another PCI-E card and a PCI card still nothing. Anything else I should try before getting a new motherboard to test it? Thanks.
