So, yeah, today I installed a Radeon 6670 HD or something like that. It was working all righty, so I decided to uninstall everything that said the word Nvidia in the add/remove programs. After that, I wasnt able to play games. I updated all the drivers of my new graphic card so Idk what the problem would be. One message I got trying to play heartstone was that I had to make sure I had at least Directx9 and that I was lacking direct3D, but I have directx11. Any solution?
