I have the same issue as the original post.
I have tried to flash the bios, update the bios with original settings, and do Fresh Windows 10 install with all latest updates. I have also updated the Intel and AMD drivers from manufacturer, my laptop manufacturer’s website and also have tried previous AMD driver versions.
The Intel driver works fine.
The AMD driver causes the screen to freeze and go black as soon as you install it. This happens with stand alone driver from Microsoft, doing device manager driver install only and also using the AMD provided driver package.
Error is “Driver Stuck In Device Thread”, meaning there is an issue with the driver and Windows 10. My machine is now crippled by either AMD or Microsoft. =((
