Windows 10: Black screen of death, sort of... But only on admin account

I have the oddest problem which doesn't seem to fit with any I can find reference to, perhaps someone could help?I have two accounts on my computer, mine as admin and one for my wife. When she logs on the computer boots straight through and finds both monitors, but on my admin account it black screens for about 10 minutes I can get to the Task Manager during this period with the 3 finger salute before the icons/task bar appears and it will only find one monitor.I'm not really one to play with settings so the install is unmolested from standard; Windows 10 Home version 21H2, all display driv

I understand that you are facing black screen issues in Microsoft account(Admin account) and unable to open Settings app on other user account. Correct me if I am wrong.

For the issues with Back screen errors on admin account, I suggest you to

For the issues with accessing Settings app on your account:

Let us know what exactly happens when you try to access Settings app?

I suggest you to run SFC scan and check if it helps.

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. If a
Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected.

Follow the below steps:

• Right click on the Start button, click on
  Command Prompt (Admin).
• Type “sfc /scannow” without the quotes and hit
  Enter.
• After the scan, restart the computer and check for the issue.

Hope it helps. Reply to the post with an updated status of this issue for further assistance.

Almost Black Screen of Death?


Okay, so my sister was trying to watch a Blu Ray DVD in my computer last night, but of course it didn't work. She ended up watching a normal DVD and it was fine. After she finished, I turned off my computer normally. This morning, however, I tried turning on my computer and it gave me the normal code screen thing with quite text and a black background. This time, instead of booting normally it said "Press [Esc] to boot... (instert countdown here)" I waited and didn't press anything and it just came to a screen that was almost black and almost blue. The cursor didn't pop up and when I pressed Crl, Alt, and Delete it went back to the white text code screen. I attempted pressing Esc like it said, but it all led back to the almost black screen of death.
I called my one of my family members for help because they are a tech guru, and they suggested unplugging everything (which I had done and proved unsuccessful), taking out the RAM and putting it back it, and still nothing. They then suggested pressing F8 when I boot up my computer, and it comes to the pop up window with two things to select. One that's called Sata and the other that's called CD or something. I tried selecting both of them, but yet again, the almost black screen of death.
After my several attempts, my family member told me to try to safe reboot using the CD we have saved for my computer as a backup. There was no DVD in my computer during all these attempts.
Was this caused by the Blu Ray, and any ideas on what to do? Thanks!
