I have been racking my brain over this one. I am trying to run an SLI set up.
I have current bios updated drivers and still Vista only recognizes one
video card. I have searched other forums and I have yet to find a solution.
If anyone has any advice for a fellow gamer please help. my System specs are
below;

Q6600
ASUS P5N-D MOBO
4G OCZ DD2 800
500 GIG WD HD
2X 8800 GT
880W PWR SUPPLY

Have you opened the nvidia control panel or Display
Properties and ensured it is in the SLI multi-GPU mode?

Does the BIOS indicate you have SLI-Ready Memory is Enabled?

I'd make sure you have the power cables connected to the second card and if
you are using a splitter of some kind that you are not sharing the same
plugs with the other card. And since the newer boards don't have a
circuit board to flip from single to SLI on the mother board anymore I
believe there is a setting in the BIOS to enable/disable SLI still.

Re: VISTA WON'T RECOGNIZE 2ND VIDEO CARD.

well thanks guys for your input. I believe that I just confirmed my worst
fear. Its a bad PCI-E slot on the motherboard. According to the manual I
should be able to run a single card in either slot and it should work. So I
remove a card and switch them around both cards will power up but my monitor
stays blank when I have one in the black slot. :(

So now I have new problem since I am going to have to RMA the motherboard.
Hopefully Microsoft will let me reuse my vista disk.

Re: VISTA WON'T RECOGNIZE 2ND VIDEO CARD.

You won't have any issues with reinstalling Windows. Even if it is an OEM
copy it will be OK since the mobo isn't really changing, just being replaced
by the same model.
