Most likely it’s an internal Windows driver issue. The driver was updated and failed, or wasn’t updated and failed, or something like that. Most commonly reinstalling the display driver resolves the issue. In extreme cases (I haven’t seen this in Windows 10, but I imagine it’s possible) reinstalling Windows may be needed. Don’t do that unless you are certain that you need to, and make sure to have complete and redundant backups.

Much less commonly it’s a symptom of a partial hardware failure.
