Kernel-Power Event ID 41 error, System has rebooted without cleanly shutting down

Windows Kernel Event ID 41 is a common error to find on out in the Event Viewer on Windows 11/10/8/7 and Windows Server. Microsoft has published an article about ways to fix those issues.

Fix Kernel-Power Event ID 41 error

The system has rebooted without cleanly shutting down first

The symptoms are that your computer restarts and a critical error message is logged in the event log:

Log Name: System
Source: Microsoft-Windows-Kernel-Power
Event ID: 41
Level: Critical
Description: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Why does the system generate Kernel-Power Event ID 41 error?

The kernel power Event ID: 41 error is generated under different scenarios where the computer is shut down or restarts unexpectedly. When the computer that is running Windows is started, a check is performed to determine whether the computer was cleanly shut down. If the computer was not shut down correctly, a Kernel-Power Event 41 message is generated. In the following three scenarios, an Event 41 may be generated

How to fix Windows Kernel Event ID 41? How to find the root cause of it?

In this article, Microsoft has mentioned three different scenarios of why this happens and how to fix it.

1. The computer restarted, and there is a Stop error BugCheckCode in the event data
2. Shut down the computer by pressing and holding the power button
3. The system randomly restarts and no Stop error BugcheckCode is listed, or the computer is completely unresponsive (hard hang)

You may carry out the following suggestions to resolve the issue:

• Disable overclocking: If the computer has overclocking enabled, disable it. Verify that the issue occurs when the system runs at the correct speed.
• Check the memory: Use a memory checker to determine the memory health and configuration. Verify that all memory chips run at the same speed and that every chip is configured correctly in the system. Run Memory Diagnostics Tool.
• Check the power supply: Verify that the power supply has enough wattage to appropriately handle the installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices can require more energy than the current power supply can provide consistently. If the computer logged Event ID 41 because the power to the computer was interrupted, consider obtaining an uninterruptible power supply (UPS) such as a battery backup power supply. Also, run the Power Troubleshooter.
• Check for overheating: Examine the internal temperature of the hardware and check for any overheating components.
• Set the system to its default configuration: If you perform these checks and still cannot isolate the problem, set the system to its default configuration and verify whether the issue still occurs.
