Try glsetup -- it automatically detects and installs drivers for you:

Edit: scratch that. The thing is ancient -- only works with win9x, lol.
Edit2: Try this. Right-click on the desktop, go to "Properties" then the "Settings" tab and click on the "Advanced..." button. See if there's a Geforce FX tab on there. If not, you didn't install the drivers properly. Make sure you have administrator rights when installing drivers.
