[SOLVED] CTD on Create User! Please help!

Yeah I'm not reinstalling Windows 7 to then find it happens again. I know that's overkill because other than this error EVERYTHING and every game runs perfectly on my system. It's as clean as possibly can be short of a full wipe.
MY method of uninstalling and reinstalling drivers was as follows:
- Uninstalled Physx via add/remove programs
- Uninstalled Nvidia update via add/remove programs
- Uninstalled 3d Drivers via add/remove programs
- Uninstalled Graphics drivers via add/remove programs
- Ran Driver Sweeper and cleaned Graphics and Physx registry keys.
- Restarted in safe mode.
- Executed nVidia setup via run as admin.
- Installed drivers using custom install option and checked box for 'Perform clean installation.'

To my knowledge that's about as clean an uninstall and reinstall of drivers as possible no?
