I have just built a new PC. The Motherboard is a ASUS P8P67 Deluxe and my graphics cards are two PNY Nvidia GTX 460s. My SLI worked wonderfully however, after installing a new heatsink for the CPU, for some strange reason, my computer only recognizes the one graphic card.
I am not sure if the Heatsink has to do with the problem. My second card does not show up in device manager, the computer acts as if theirs only one card. I tried each card in the first slot and they both work. I've tried turning the computer on with only one card in the second slot and it won't display. I guess it could be a bad slot but it worked perfectly prior to the heatsink.
What are some tests that I should perform to better troubleshoot the problem and find a fix. My OS is Windows 7 64bit. And I have tried reinstalling windows 7 and that did not fix it.
