So I recently installed a used RX 470 Strix into my friend's computer as the old GTX 570 I sold him about a year ago died, and I'm having trouble with the drivers. I made sure to delete the drivers for the HD 5770 that I let him borrow in the time between his old card dying and getting the new one. When I installed the RX 470 drivers, there was no audio and I was getting error messages when opening games saying that I was missing files required to play the game. I tried to open the AMD software, but it told me that there were no AMD drivers installed on the system. I tried uninstalling the drivers with DDU and reinstalling them, but I got the same errors. Any possible fixes for this?
