[THE G33K]

Greetings

I have 2 nvidia evga geforce 9800 gx2 video cards for my system. I know both of them work seperatly becquse i can get my system to post and boot into windows, but my system wont post when i have both cards in at the same time. When i have one card in i get a blue (primary) light on output port one and a green light on output port two. When both cards are in i get no light on port one for both cards and a green light on port two for both cards. I would like to be able to get the system to boot up with both cards in and working so that i can have either four outputs for four monitors for max display or one video card dedicated for one output on each card for max graphics display.

I lknow that i got it working before i reformated my computer, i cant remember if i had it working on xp pro x64 or vista x64, but i am running vista x6s right now.

Any sugestions are apretiated.
