Sli not detected

I have 2 8800 gtx ultras and they are currently linked in sli. When I installed windows 7 it no longer see's both the cards. There is no option in the nvidia control panel to enable sli like it used too. I have updated all my drivers from the mother board to the graphics cards. Still nothing. I tried running each card on its own and they work fine. I just can't get it to detect the second video card in sli. Any help would be greatly appreciated.

Check out this thread at another website, it may help you.
