Alienware laptops are super picky about driver versions. Ask me how I know, lol. If support.dell.com doesn't have anything for your service tag that works, then it can be difficult. I've saved the versions that worked for me with my stuff (no sli I'm afraid) but I do have an old installer for the geforce 7700 (version 7931) - that's the closest I have to yours.
Anyway, I did come across this site that has archived links for the developer downloads for the drivers from nvidia (everything else I could find was from some shady looking 3rd party). Hopefully, you can find a version that will work with your config:

Maybe this one? developer.download.nvidia.com/opengl/2008-12/NVIDIAGPUVista(181_00).exe
