Windows 10: How to fix partial black screen that's moving along with the cursor?

I have this windows 11 problem that I can't find anywhere on YT or Google.Everything seems fine when I launch Photoshop but when I use the brush tool a partial black screen appears. The cursor sits on top of it and the black screen moves along with the cursor. Meaning you can't see the black screen when I put the cursor at the bottom and the screen will go completely black if I hover to the very top.This also happens when I use Da Vinci resolve. When I drag an effect to the timeline same thing happens.Same problems happened in excel. But I seemed to fix it when I disable hardware graphics acce

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?

 

Random black screen moving the cursor

Hi.

I have a problem I hope someone can help me out with.

My Asus computer randomly started to get black screen this happens when I for an example sit on facebook and maybe play some game.

After like 10 minutes a spot on the screen starts to turn black and when I move the cursor around its kinda "painting" the rest of the screen and it will all go black. I can let it stay for hours and it wont come back.

I have to manually kill the computer by pushing the turn on button for a few seconds.

Any suggestions ? please
