If your graphics card is not supported by the drivers chances are that you are pretty bummed out by now. You might try this little trick.

In this directory you see a notice .inf file, copy and replace this over the .inf file from the installation (setup) directory.

Now please manually install the driver. This means you need to skip the setup.exe as you need to install these the old fashion way:

> Control Panel > System > Hardware > Device Manager > Diaplay Adapters > your graphics card > Driver > Update

Please be sure to properly uninstall your current graphics card drivers before installing new ones.

This modified .inf file supports all NVIDIA graphics cards and laptops to date. If the driver set was WHQL certified it'll loose that WHQL stamp though. This should not affect the drivers in any way.

Should you have any questions or run into problems then be sure to visit the NVIDIA support forums over at Guru3D.com
