I've meticulously followed the advice of a clean install (a process I follow anyway) by uninstalling everything, emptying the C:\AMD folder, disconnecting from the internet and restarting in safe mode, cleaning with DDU, then installing the new drivers. My PCs device manager automatic installation settings to 'No'.
I've also changed the registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DriverSearching to '1'.
My PC continues to revert back to the 17.1.1 driver.
What can I do now?
Any help/advice very gratefully received.
