Windows 10: PC keeps restarting after sign in

This Windows 11 keeps on restarting after sign in. I cant get to my desktop and run my apps. It is just keeps on restarting then ask for sign in again. I dont have this issue when I running Windows 10 but after upgrading to Windows 11 I keep getting issue and now this.

How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.

It wouldn't let me do anything really so i went to restart my pc and it keeps saying wrong password and won't let me sign in.

PC windows 10 keeps restarting

Hello Cynthia,

We regret for the inconvenience. Let me assist you.

Before we proceed further, let us know a few more details on the below questions.

• What is the make and model of the PCs you are using?
• Did you make any changes to the PC prior to the issue?

As an initial recommendation, I suggest you to boot the computer in safe mode with networking, and check if the issue still persists. This is a diagnostic step towards identifying and isolating the possible cause/s of the issue.

Safe Mode With Networking:

Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words
Safe Mode appear in the corners of your monitor to identify which Windows mode you're using.

Refer: Start your PC in safe
mode in Windows 10

Refer to the section From the Sign-in screen

If you are able to start the PC normally this time. Use the following steps to disable automatic restart in Windows on system failure.

• At "Start" -> "This PC" --> right click on "Properties", and then tap "Advanced system settings".
• In Advanced, click on "Settings" for Startup and Recovery.
• In the Startup and Recovery window, uncheck the Automatically restart check box.
• Click OK.
• 
  Now if the computer generates an error, it should not automatically restart
  

Once this is done, reboot the computer in normal mode and check.

Let us know the updated status and the required information for us to be able to assist you further.

Thank you.
