Will try removing driver firstWelcome to the forums, newcomer!
I just upgraded my gpu from rx550 2gb to gtx 1060 3gb and it just give me a black screen please help
Did you run DDU in Safe Mode to remove all GPU drivers(Intel, AMD and Nvidia) to later install the latest version from Nvidia's support site, in an elevated command, i.e, Right click installer>Run as Administrator?
Just an FYI, you should've looked into the 6GB version of the GTX1060. Make and model of your PSU and it's age?
Yeah everything fine but i fixed the 1060 now so i run perfectly fineJust out of curiosity, is the CPU and board below what you're currently using? If you swap back to the RX 550 2gb, does the computer boot properly again?
