Two Versions of Nvidia Physx Causing Conflicts?

[Ivan Drago]

I am getting BSOD which seems to be due to my display drivers. When I tried to delete all the old drivers before getting the newest ones, DriverSweeper wouldn't let me delete the Nvidia directory on the C drive. Now I seem to have 2 versions of Nvidia Physx - how should I go about getting rid on the old one if this is the right thing to do?

The locations are:

C: > Nvidia > DisplayDriver > 191.07 > WinVista_Win7_64 > English > PhysX_9.09.0814_SystemSoftware

C: > Nvidia > DisplayDriver > 196.21 > WinVista_Win7_64 > English > PhysX_9.09.1112_SystemSoftware
