Error Kernel-Power code: 41 in Windows - causes and all solutions

If your computer reboots frequently for no reason, you may encounter a critical Kernel Power 41 error. The kernel is a central part of the operating system, and its failure causes the PC to reboot. You can check for errors in your PC's event log. It most often occurs when running games and other demanding processes. Sometimes this error also causes BSOD (blue screen of death) with error 0x8000400000000002. Also, many users receive the message “The system rebooted without first stopping. This error may be caused by the fact that the system has stopped responding, a failure has occurred, or an unexpected power outage. ” This problem affects not only Windows 10, but also previous versions of the OS.

How to fix the error "Kernel-Power code: 41".

What does the Kernel-Power error mean? 41

The Kernel-Power error message (ID 41) states that the system was rebooted without first shutting down. This can be caused by the fact that the OS stops responding, it crashes, or an unexpected power outage occurs. More precisely, the error occurs when the computer suddenly turns off or restarts. A critical Kernel-Power Event ID 41 error is generated when the Windows-based computer starts up after its last shutdown, and the OS detects that the previous shutdown was performed incorrectly. Event ID 41 reports that something unexpected has happened that does not allow Windows to shut down correctly.

Causes of failure and remedies

The error message itself provides a lot of information, and therefore it is important to know what the computer was doing right before the event and determine a potential solution. Insufficient or faulty power supply can be one of the main reasons. For example, if you recently added random access memory (RAM), additional devices, or hard drives, and then encountered an error, the cause could be a power source. Among other popular causes of the error Kernel-Power 41 in Windows 10 and others:

  • Incorrect, damaged or outdated drivers.
  • Incorrect BIOS settings.
  • Antivirus software.
  • Power settings.

Here are some more examples of this problem:

  • Kernel Power Error in Game - Kernel 41 power error usually occurs when starting games.
  • Core Power Event 41, Task 63 Windows 10 is another version of Core Power Error 41.
  • BSOD Error 0x8000400000000002 - Kernel Power 41 usually causes a BSOD followed by error code 0x8000400000000002.

In the guide below, there are several possible solutions for fixing Kernel-Power errors. They relate to the Windows operating system and settings that may cause problems.

Driver update

Microsoft constantly releases various updates to improve the overall user experience of Windows. But such an event can bring a lot of pain, as some of them make the system completely unusable. So, check to see if Kernel-Power 41 has a problem after installing the latest update, and whether it should be removed. Follow the instructions to do this:

  • Click Windows + I, open the Settings app.
  • Select "Update and Security", click "View the history of installed updates."
  • Select "Remove Updates."

Now check if the bug is fixed or not.

RAM check

Another common cause of a kernel malfunction in Windows is random access memory (RAM) when it is not properly connected or the slot (or the bar itself) is dusty. To detach the RAM, it is enough to bend the special clips on the sides of the slot. Remove the chip, remove dust and dirt, and put it back in place. Do not do this when your computer is turned on or connected to a power source. When finished, reconnect the computer to a power source and turn it on. Check the system for performance. The next step is to use the built-in Windows memory diagnostics tool. To reach it, open the control panel and click "Administration". You can also open a start and enter “memory” in the search field. You will see a link to diagnose problems with the memory of your computer.

You will then be asked if you want to restart the computer immediately or run the test the next time you restart. The computer boots into the diagnostic tool and starts the test, which is divided into two separate stages. Below you will see the “Status” field, in which the detected problems will be displayed. You can also press the F1 key and change several parameters, such as the type of test (basic, standard or advanced), the cache settings and the pass counter.

Diagnose with memtest86

memtest86 is by far the most popular RAM check tool that has been in existence since the 1990s. To use it, you must burn the ISO image to a CD, and then set up your computer to boot from the disk. After booting from the CD, you will see a menu with several different options. By default, the first option will be automatically selected. The memory test will start, and if there are errors, a message will appear in the lower right corner. Memtest86 has several memory tests, so the process takes a little longer than the Windows memory check tool. It is a great helper for every administrator and is largely an industry standard for memory diagnostics. There are other tools that perform similar memory checks, but memtest86 is the most comprehensive and accurate of all.

A critical Kernel-Power error is usually related to power and indicates that something is wrong with the computer's power supply. The reason may be oxidation on the rear panel of the device switch. In this case, contact a specialist to check the power supply - a replacement may solve the problem. Another possible cause of this critical error is overheating. The computer usually turns off when the temperature is too high. You can download the SpeedFan program, which controls the temperature and checks whether the PC components overheat when the computer is turned on. Make sure that all the wires are connected correctly (inside and outside the computer unit), and check that the power connectors for the graphics processor and the main (motherboard) are properly connected. In addition, remove the processor and reinstall it (if you have practical skills and experience of a similar procedure).

Change BIOS settings

BIOS (Basic Input Output System) is software that is stored on a small memory chip on the motherboard. To update the BIOS, go to the motherboard manufacturer's website and download the latest BIOS for the motherboard. There should be a manual describing how to update the BIOS - make sure you read this carefully. Keep in mind that a BIOS update is a procedure for experienced users, and, if not performed properly, could cause permanent damage to the hardware. If you do not know how to update the BIOS, find an expert to avoid damage to your computer. Most IT specialists have come to the conclusion that changing certain background modes in the BIOS and in Windows 7 and others can also help in fixing the problem. To do this, follow these steps:

  • Turn off the computer.
  • Now turn on the PC and enter the BIOS by pressing the BIOS key during system boot. The BIOS key is usually displayed on the boot screen that says "Press ___ to enter the installer." Common BIOS launch buttons are F1, F2, Del, Esc, and F10. Please note that you need to act immediately after turning on the PC, since the message disappears rather quickly.
  • Find the Power section. It is located on different tabs of the BIOS firmware tools, depending on the manufacturer, and there is no unique way to find it. It is usually located in the Power Options section or something similar to this, and is called ACPI Settings.
  • Find the "Enable Sleep Mode" or "ACPI Features" option and make sure they are enabled. Below you should see the ACPI sleep status or ACPI sleep status options, so make sure you change them from S1 to S3.
  • Go to the "Exit" section and select "Save Changes and Exit."

After reboot, check if an error appears.

Eliminating the conflict of two sound cards

Some users get a critical kernel-41 kernel power error due to a sound driver, so be sure to check for duplicate drivers and disable drivers. Follow the steps:

  • Press the Windows key + X, select Device Manager and open it.
  • Now find the audio drivers in the sound, video and game controllers.
  • If there are any duplicate entries, right-click one of them and select “Disable” in the menu.

If your system does not have duplicate audio drivers, try disabling audio drivers from the lists. Some users have reported that disabling the ATI High Definition Audio Device from the device manager solved the problem. However, you can also try to disable any other audio device driver to fix the problem and check if it helps to fix the error.

Other ways to get rid of the error

You may have encountered a critical Kernel-Power error associated with event identifier 41. It is usually observed in Windows Event Viewer, which displays a log of system messages and application messages, including warnings, informational messages, and errors. Often there are a lot of errors in the event viewer, but if your computer works fine, you can ignore them. However, you should not ignore the critical error Kernel-Power, as it may affect the stability of Windows. Right-click on the My Computer shortcut and select Properties-Advanced System Settings-Startup and Recovery Options, and turn off the Automatically Restart option in the System Failure section. Open the registry editor by typing "regedit" in the search bar or in the "Run" dialog box, and go to the following key:

HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet \ Control \ Power \

Find a REG_DWORD with the name “HibernateEnabled” in the right part of the window, right-click it and select “Change.” Change its value to 0.

We hope this guide was helpful and helped fix a critical Kernel-Power bug (ID 41). If none of the methods mentioned above solved the problem, it may be hardware related and you should contact a computer specialist to check the system.
