Windows 10: Dark screen during start up prior to log in

Windows 10 will not boot up and I tried the steps provided with no help. Any advise?

:)

 

Black Screen after Log on


Computer boots to windows log on,have no password here.After a minute on log on it go to a black screen,stays there forever. I can get to Task Manager from black Screen,lost on what to do next. Just want my Windows 10 back, not sure what caused this problem. Any Suggestion on what my next step should be?*Sad

 

Re-started Windows Explorer: My screen went blank/dark blue

1. My taskbar disappeared first. I opened task manager and found Windows Explorer at the bottom of the processes.

2. I pressed re-start and normally, the screen goes back to normal. I didn't do the steps you list in 2.

3. No. I just get the list.

4. I restarted my computer and nothing changes. I turned it off and waited, then turned it back on. I get the sign on screen. Enter my password and then the dark blue screen appears.

That 's it.

 

Lock Screen setting prior to log in

There is a screen that appears prior to logging in - I initially "somehow" set this to a picture, which I don't want. I can change the settings for my account once I log on but not this initial screen. Anyone?
