Hi all, I have just bought a 2nd 8800gt to use SLI with my original, and hit a problem. I can't get the card in the 2nd pci-e slot to work. Both cards work fine in the first slot. So far, I've tried with the SLI bridge, without the bridge, and by just putting a card in the 2nd slot, and nothing has worked - a card in the 2nd slot doesn't send any output to the monitor in any configuration. I've got a 700w SLI PSU, which I have just upgraded to see if the old PSU was the problem. Has anyone got any suggestions for anything else I can try? Thanks for any help.
