I uninstalled my laptop's AMD drivers completely to clean install the new drivers. Now the display resolution changed to 800 x 600 and my graphics card isn't showing up on the device manager. I have 2 cards an AMD radeon hd 6520G APU and a radeon HD 7670m card. The 7670m isn't showing up, instead it's called standard Vga adapter. Both the 6520G and the standard Vga have a small yellow triangle next to them in the device manager. I did a system restore but it didn't help. Can anybody tell me what to do now?
