Windows 10: Black screen with cursor, task manager not working, safemode boot no working and can't sign...

I do not have access to a USB drive at the moment.Problem: Windows boots to a black screen with only a cursor. Win +P shows the screen menu.Cause: seemingly nothing, the night before it worked fine and unless it updated while it was booting in the morning I do not think a windows update caused itTroubleshooting tried: cant bring up task manager, the screen remains black and the same goes for ctrl alt del.Unplugging everything didn't work, switching cables didn't either.Ctrl shift Win B did nothing other than centering the cursor.Booting in safe mode didn't change anything.Booting in the smalle

Black screen with cursor


Living in Fear: Updated to Ten (Gateway SX-2800), it worked for a month.
After an update came black screen with cursor. TenForum solution (3
shutdowns before full start) and restart fixed. Updated video and other
drivers. Another update event, happened again, this time auto fix did not
fix. Advanced to system restore. Worked once. I was on a special project,
feared same problem, so I left computer on for 2 weeks, no problem. Then
was forced to restart with update. (BTW -sorry didn't mention *SadI GET THE SIGN ON
SCREEN EACH TIME , AND ENTER PASSWORD) then black screen - and now no fixes
work, no restore points. Current status - active cursor, notifications and windows pop up
over a black screen, addressing second monitor with blind keystrokes on and
off works (evidenced by cursor), task manager opens (ctrl alt del) and
seems fully functional. Lots of functions in task manager show stopped.
Seems like desktop is there but screen is black. Any possible fix through
task manager or by keystrokes?? tried all fixes found here. Help!!

 

Black screen with cursor


Have a Gateway SX2800-01 which has (had) Windows 7 Pro installed. Finally gave in to Window 10 upgrade prompting and said yes. Ten installed well to my surprise, it ran for several months. Then on an update it restarted to the sign in screen, password, then black screen with cursor.*Sad I found TenForums and possible solutions with my laptop.
First try - partial boot 3 times - brought up auto fix - after running - chose restore point I had set in - IT WORKED.
I updated the video driver just in case that was a cause of problem.
*Sad The install update came up again. I held off for weeks. Finally gave in. Restarted with sign in screen - then black screen.
*SadSecond try - 3 partial boots - fix screen options - one available earlier restore point showing -tried - DID NOT WORK THIS TIME- Black screen again.
*SadThird try - tried option 'start to safe mode' - Sign on screen - password -still BLACK SCREEN
Tried (from TenForum) blind keystrokes to activate second monitor. It worked evidenced by cursor showing on second black screen (off -no cursor on second screen). Tried removing monitor and devices. The only option left from partial starts and auto fix, is to restore toan earlier Build - but I believe will likely give me another black screen.
Observations - notification windows pop up on black screen (example: "your antivirus has been updated"). Ctrl alt del opens 'task manager' window over black screen. Tabs work showing active activities of files/programs.
I don't know about fast start mode. Can that be accessed from task manager? Or something to get my desktop back?

It is frozen or just black screen in Safe mode ?
