First, download the NVIDIA driver that you'd like to have installed.
Then, install Driver Sweeper 3.2.0 (it's the last version released before it became Driver Fusion): http://www.techspot.com/downloads/4266-driver-sweeper.html
Then, open the Programs and Features control panel and use that to uninstall the NVIDIA Graphics Driver and PhysX.
Then, reboot into Safe Mode.
Once you're in Safe Mode, open Driver Sweeper.
Select "NVIDIA - Display" and "NVIDIA - PhysX".
Now, click Clean on the lower-right corner.
It will ask you if you want to reboot, so say yes.
Once you're back into Windows, install the driver. Use the custom installation and deselect anything that you don't need. Then, install. You do NOT need to use the Clean Install because you already did that (and more) with Driver Sweeper.
Now, reboot after the installation is complete and you should be all set.
