Hi, wecome and i understand your issue, but tip for future use: dont go "im switching to <some>", gives people a bad vibe from you post. I get that you are frustrated, you made a good point that its important too you.. (and end there, people tend to help to who seem to need help more often than a person who could just explode in their faces.
Just a suggestion, take it or leave it...
Now your issue ... i tend to have the feeling that there is version conflict with driver & softwaresuite .. had those with both NV, AMD and most recently Intel
Its possible that with your driver package, windows update decides their WHQL versions are newer or required. So after you install the driver, at reboot WU installs its driver ..
Speedrun test:
- if you have an other disk with space.. install new os to that disk, update & and do AMD drivers (chipset..reboot..gfx), check updates again..
