If you’re getting the so-called ‘black screen of death’ as described in the BBC News article here, then try this workaround.
When you restart your computer after a black screen incident, try pressing F8 repeatedly right as the machine turns on.
Normally, this would allow you to boot into the various operating system start options (like safe mode). I have found that this allows Windows to start normally, though it leads to another unusual bug where hammering F8 boots up the machine normally instead of giving you the system start options.
I’ll see if I have a few minutes to post a video on it later. Good luck.
