    Download the newest drivers for the card from nVidia's website, and install it.  It should reinstall PhysX if it is applicable for your card (I'm sure it is, as new as your video card is).

That's probably the issue. Driver Sweeper normally causes more problems than it solves, it often deletes .dll files and registry entries that you actually need.

Ive heard that if you rename that NVIDIA corporation folder it could help. Installing Physx is a B if it doesn't install correctly on its own)

Try this:

http://www.nvidia.com/object/physx-9.12.1031-driver.html

and if that don't work, try this:

http://support.microsoft.com/mats/Program_Install_and_Uninstall

This will help remove PhysX. I just went through this.

    Has any progress been made yet?  The thing I would look into next would be NTFS permissions.  I've come across two computers so far that the NTFS permissions got messed up badly, one in the registry and the other on the HDD.  This could cause the installer to fail to write needed files (or make the written files inaccessible); however, it could be somewhat complicated to debug, though.
