This is driving me nuts!
Windows update didn't install a driver - and using the latest adrenaline drivers gives this error.
Have tried removing the drivers using the AMD cleaning tool, turning off driver signing, and also checked out all the possible fixes in the 1603 error screen, but nothing worked.
Guessing it's due to it being a new chipset that it has issues.
It's a 7940HS in a GMKtec mini pc. Is anyone else still having issues with these drivers?
