Hey I have the same problem over here. I am currently running a GF4mx (pci) in my C2D system (3.8 ghz, 2GB ram) and I tried to install the latest driver (93.71) for my videocard. At first the driver doesn't recognize the OS, then windows pops up saying it can use backwards compatibility. It installs alright, but as soon as I launch a 3d-app or want to have the system benchmarked I get a BSOD:huh: (talking about the nvidia driver). It probably has to do with the limited control the driver can influence and Windows 7 will need to allow it for everything, but I have no idea how to do that. I think there will be lots of people with these kinds of problems with no updated drivers available.
