I'm experiencing a catastrophic boot failure on my Win10 box. Each time I boot, the system hangs on a black screen before the login screen. The keyboard and mouse are unresponsive; even the num lock / caps lock lights do not respond to button presses in this state. The same issue persists in a clean boot with everything disabled. However, I am able to get the machine to boot into Safe Mode, so I can at least do some basic things.
Based on my reading, I have a hunch that there is a driver problem. My plan to diagnose it was to disable everything in the Device Manager and then try re-enabling devices one by one. But, I'm a bit nervous about this plan; I don't want to do anything irreversible, and I don't want to lose my limited Safe Mode functionality. In particular, I'm worried about what will happen when I disable fundamental things like those related to the motherboard or display adapter.
My question: is it risky to disable all devices in the Device Manager?
