Mass effect 2 nvidia physx error

[tuunade98]

when i try to load up mass effect 2 on my PC it gives an error saying failed to initialize the physics system please install a later version of physx or something like that so i went and download the latest nvidia physx or Ageia physx then i tried installing it but everytime after the licence agreement i would get installation ended prematurely because of an error can someone please tell me how to fix this

what you could do is uninstall ALL nvidia drivers then use driver sweeper to clean the physx and left over driver files and registry strings, then reinstall the latest driver. (DO ALL OF THIS IN SAFE MODE)

i've got an ATI radeon 4670HD im pretty sure i have no NVidia drivers on my computer and yeah this is getting really frustrating
