Windows 10: Multiple issues regarding Black Screen and issues with administrative privileges

Whenever I log into my pc I keep facing a pitch black screen for 5ish minutes. I tried Ctrl+Alt+Del to open the task manager and restart Windows Explorer but Task Manager didn't show up. I waited for 5 minutes and finally, my desktop showed up. But I still can't open the following: Task ManagerCMD as administratorDevice ManagerRunRegistryIt says Windows cannot access the specified device path or file. You may not have appropriate permissions. So to sum it up, I lost my administrative access even after I tried to give my User account full control in the safe mode, and I get a black screen for 5

Issue with black screen, dual display, ATI Integrated GPU

Hi,

I suggest you to follow the below methods and check if it helps.

Method 1: I suggest you to go to device manager and disable the display drivers, check whether the issue persists or not.

• Press Windows + X keys and click
  Device manager.
• Click to expand Display adapters, right click the second adapter and click
  Disable.
• Restart the computer and check whether the issue persists or not.
• Repeat the same steps to disable the first display adapter and check if it helps.

If you find the issue is with anyone of the display adapters then, I suggest you to update the display drivers from the manufactures website for Windows 10 and check if it helps.

Method 2: I suggest you to follow the steps form the below article for
“Black Screen” issues and check if it helps.

Black screen issue

Hi Bojan,

Thank you for posting in Microsoft Community.

I understand the inconvenience you are facing in Windows. We will help you.

Meanwhile to understand the issue better, I suggest you to answer some below questions.

• Are you able to Boot till the login Screen?
• Is there any cursor blinking right or left side of the display?
• What is the make and model of your PC?

This issue could occur due to incompatible, outdated or corrupted device drivers. You can also check if detaching all other peripheral devices except for keyboard and mouse works out the issue. The issue (black screen) you’re facing could be most likely
related to display drivers and could be resolved by updating the drivers. Without the correct driver, the hardware or device that you want to use won't work properly.

I would suggest you to refer to the suggestion by Sharath Srinivatava
from the following link and check.
