Troubleshooting in a clean boot state

View event log

let's start

1]Adjust power settings

First, you need to start adjusting the power settings. Doing so can help resolve conflicts between different energy-saving features or software that may be causing lock screen issues. Follow these steps:

• Go to Control Panel.
• Click on Power Options.
• Click to change plan settings.
• Set both to turn off the display and set the computer to never sleep.

2]Run SFC and DISM scan

System file corruption or errors may cause this problem. You can scan the system image file to solve it. Open a command prompt and run the System File Checker tool as administrator.

If this doesn't work, we'll run DISM in Command Prompt (Admin) and see if that helps.

3]Update GPU driver

You can go to the computer manufacturer's official website to download the latest GPU driver. Before installing the driver, be sure to use DDU to completely delete the existing display driver, and then run the installation file to complete the installation of the new driver.

4] Disable hybrid sleep (if applicable)

Check if Hybrid Sleep Mode is activated on your computer. If it is, disable it.

5]Troubleshooting in a clean boot state

A possible cause of this error is a conflicting third-party application or service. Start the computer in a clean boot state and check if the problem persists. If your computer does not restart when locked, a third-party application or service is responsible for this error.

Now, you must identify the problematic third-party application or service. To do this, follow these instructions:

• Use Task Manager to enable some startup applications.
• restart your computer.
• Check if an error occurred. If not, enable other startup applications and restart your computer.
• Check for errors. If so, one of the apps you just enabled is the culprit.
• Now, disable one of the applications and restart your computer. Follow this process until the error goes away.
• When the error disappears, the app you just disabled is the culprit.

Similarly, you can also find problematic third-party services. But this time, you have to use the msconfig application.

6]View event log

Whenever an error occurs on your computer, Windows creates an event log. All these errors and warnings are logged for troubleshooting purposes. These event logs help users and developers troubleshoot and fix errors. We recommend that you view the event log in Windows Event Viewer to get some clues as to why your computer restarted when it locked up.

• Click Windows Search and type Event Viewer.
• Select the best match from the search results.
• After opening Event Viewer, expand the Windows Log folder and select the System folder.
• Now, the error is found based on the date and time the computer was restarted.
• Select an error and read its description.

You may see different event IDs like

Event ID 41, the system has restarted but not completely shut down in Windows 11/10

The above event ID error occurs when the computer is restarted without a complete shutdown. There may be many reasons that trigger this event ID error, such as overclocking, RAM failure, power supply unit failure, overheating issues, etc.

Based on the error message displayed in the event viewer, you can continue with further troubleshooting. You can refer to the best help and technical support websites for assistance with errors displayed in the event viewer.

I hope this helps solve your problem.
