Windows 10: Black screen after logging in to my pc

For a few weeks when I would turn on my pc I would just be met with a black screen and would have to turn it on and off several times for the login screen to appear so I can login.

So this would reoccur occasionally and I wouldn’t think much of it since the problem would solve itself.In the past week I noticed that the number of tries it took me to turn on the pc to login increased by

Laptop or Desktop (Very important) Windows 10 build 14.586 has a very annoying BUG: That causes Black Screen after login:
To date there is no cure until Microsoft send Update to fix the problem: OK here goes: When you Login and the Screen Goes Black ==>
Go to your Function Keys for Screen Brightness Chose to Lighten the Screen (This will make the screen Bright) so that you can view it.
The BUG is that they reversed (via Software) what the Brightness button does -- So it is currently reversed -- "Lighten" makes it Dark -- "Darken" makes it Bright ==> Go figure Microsoft screw the pooch on this one. . . .

This is for LAPTOP -- I have never seen this on Desktops but they are fixed rather than adjustable
