I had to use one of my brother's 2 9800GTX's as a replacement for my GTX 260 which was broken and had to wait for my ATI 5850 to arrive. I left the SLI bridge in the bottom of the case, which I fear may be the cause of the problem. When I put just one card in, everything is fine. When I try both cards and try to start up, nothing happens. And yes, both cards work fine.:O
