Can't find a working driver for Go 7900 GS

Hello,
I'm trying to get Windows 7 Ultimate (32bit) running on my Alienware M9700 but am having a hell of a time getting any graphics drivers to work. The computer defaults to the windows standard VGA adapter, and every time I try to install an actual Nvidia driver when I restart I just get a black screen. I tried several of the latest video drivers from laptopvideo2go as well as the latest official driver from Nvidia's own website, all result in the black screen. I did get ok results when I tried installing the video driver that came on my original install disk but it's an incredibly old driver (from 2007) and is actually meant for Windows XP so that's not exactly ideal.

Basically when I go to start the computer it shows the Bios screen, then goes straight into the "Starting Windows" screen where it sits for a minute like it's booting then just goes to a full black screen. It will do that until I reboot in safe mode and uninstall the drivers.

Any advice is appreciated, thanks

Also it's probably worth mentioning my laptop actually has two 7900's running in SLI.

The latest drivers I see for your laptop are:

They're for Vista, but they ought to support Win7.

With any luck, once you have the Vista drivers in place, newer installers will recognize the custom ID of your graphics device.
