I have exactly the same message as before in the manager "The best drivers for your device are already installed."

Uninstall the AMD card properly with DDU
Check out this tutorial, step 2 --> Display Driver Uninstaller

Disconnect the ethernet and wireless from the PC
Restart the PC

Reinstall the driver manually.

if I reinstall W10, could it work?
