I originally had an Asus HD7770 and just swapped it out for an MSI GTX 970. After installing the correct online drivers it seemed to work but I seem to have lost many functions.
Windows Aero transparency is gone, I cannot run the Aero test either and dxdiag crashes if I do not bypass Direct 3D. I wouldn't really care about these but I think these could be important for diagnosing the problem.
Neither Black Ops 3 or GTA V run anymore. Black Ops 3 returns the error "No valid DX11 video card found." and GTA V just appears "Not responding". My computer was working perfectly fine with both games before I swapped the graphics cards.
I uninstalled the AMD catalyst centre, Asus GPU tweak and an Asus product registration to no avail.
Any suggestions on what is wrong or how to fix my problem would be appreciated. Thank you for your time.
(I'm running Windows 7 64 bit, i5 4670k processor, 16GB RAM, 1TB HDD, 120GB SSD and a 650W BeQuiet PSU
 
I ended up going onto the control panel, disabling GTX 970, uninstalling it. Removing any programs relating to my old AMD card and then removing any folders that were named AMD or AMD related in my system files. I then enabled the card again and installed the drivers and after a reboot it worked fine. Thanks to shazzy182 for the help
