No Video Windows 8 (Need Help)

[BeeBoop]

I was running a hybrid physx setup and decided to upgrade my dedicated physx card but had no clue on how to do so. I started by uninstalling Nvidia drivers and everything went black. My AMD card is the main video card so I unplugged the dvi from AMD and installed it into the Nvidia and it worked and proceeded to uninstall the rest of the Nvidia drivers but then it went black again. I plugged the dvi into the and and it doesn't work either. So my question is, how do I uninstall all the drivers without video? How do I update my hybrid physx without having to reformat everything?

Nevermind. I did a PC refresh and it restored the system to default everything.
