RX480 Error 43 Help?

Hey all. I just put together a custom build with a Ryzen R5 1600 on an ASRock AB350 Pro 4 motherboard. My graphics card is a RX480, the Sapphire Nitro+ version. It boots fine, and the GPU puts up the basic windows display without a problem. However, it's only working on Windows Basic Display Adapter ability, I think. In device manager, it is constantly plagued by an error 43 message. I have installed all the drivers from AMD, including AMD's chipset drivers, the display drivers for the 480, and an all-in-one driver set from ASRock for the motherboard.

 

I have searched for the answer quite thoroughly and done every permutation I can think of. I have used DDU, I have used the AMD unistaller, I have uninstalled from control panel. I have installed drivers without internet, without windows defender on. Safe mode installations manual driver installations from device manager. I am worn of all the ways I have tried to get this to work for the past 24 hours.

 

I am hoping you can help me. I must admit that I am somewhat desperate. I thank you in advance for your help.
