How To Fix Kernel-Power Critical Error (Event ID 41)
You may have experienced a Kernel-Power critical error associated with Event ID 41. This error is usually seen in the Windows Event Viewer, which shows a log of system and application messages, including warnings, information messages, and errors. There are often many errors shown in Event Viewer, but if your computer is working properly, you can probably ignore them. The Kernel-Power critical error, however, is not one you should ignore, as it could affect Windows stability.
The Kernel-Power error (ID 41) error message states that the system has rebooted without first cleanly shutting-down. It can be caused if the system stops responding, crashes, or loses power unexpectedly. To be more precise, the error occurs when the computer is shut down or restarted unexpectedly. The Kernel-Power Event ID 41 critical error is generated when a Windows computer starts after its last shutdown and Windows finds that the computer was not previously shut down cleanly. Event ID 41 reports that something unexpected happened, thus preventing Windows from shutting down correctly.
The error message itself does provide much information, and why it is important to know what the computer was doing just prior to the event, and to identify a potential resolution. An under-powered or failing power supply might be one reason. For example, if you have recently added Random Access Memory (RAM), additional devices, or hard disks when this problem arose, the power supply might be the cause.
In the guide below, there are several possible solutions to fix Kernel-Power errors. These address the Windows operating system and settings that might be causing issues.

Customize Power Settings
The Power Plan feature in Windows 10 is not new and was available in earlier versions of the operating system. Power Plan is a collection of hardware and system settings that manage how your computer uses power. Here, we show how to change the advanced power settings, and customize hard disk power management and sleep mode settings. Type "power options" in Search and click the "Power & sleep settings" result.
Now click "Additional power settings" under Related settings on the right pane.
In the Power Options window, find and click the "Change when the computer sleeps" option on the left pane.
Now click "Change advanced power settings".
Now expand the "Hard disk" and "Turn off hard disk after" sections and make sure that both "On battery" and "Plugged in" are set to "Never". If these settings are configured differently and there is no "Never" option, then simply type 0 and it will change to Never. Now expand the "Sleep" and "Sleep" after sections and make sure that both "On battery" and "Plugged in" are also set to "Never". Click "Apply" to save the changes.
Update All Drivers
A device driver is a software that informs the operating system and other software how to interact with particular hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or people. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly, if at all, and in some cases cause Kernel-Power critical errors. Updates for drivers are usually installed together with Windows Updates, however, it is possible that some drivers were not updated, especially if you haven not updated the entire operating system for some time. To update your drivers manually, open Device Manager by right-clicking the Start button and selecting the "Device Manager" result from the contextual menu, or type "device manager" in Search and click the "Device Manager" result.
In Device Manager, you will see a list of devices connected to your computer. Expand the device in question by right-clicking the arrow near it and right-click the device, select "Update driver" from the contextual menu.
You will be asked if you want to search for updated driver software automatically or to browse your computer for driver software. If you select the first option, Windows will search your computer and the Internet for the latest driver software for your device. If you select the second option, you must locate and install the drivers manually. Using this option requires having previously downloaded drivers on your computer or USB flash drive - this is a longer process because you will have to download the latest drivers for all devices manually by visiting the device manufacturers' official websites. Select the option you prefer and follow the instructions.
You can also use third-party software to update your drivers automatically. In this case we recommend Snappy Driver Installer (SDI), a powerful free driver updater tool for Windows that can store its entire collection of drivers offline. Having offline drivers gives Snappy Driver Installer the ability to have access to fast driver updates, even if there is no active Internet connection on your computer. Snappy Driver works with both 32-bit and 64-bit versions of Windows 10, Windows 8, Windows 7, Windows Vista, and also works with Windows XP. Drivers are downloaded through Snappy Driver Installer in 'driverpacks', which are simply collections (packs) of drivers for various hardware such as sound devices, video cards, network adapters, etc. It can also show duplicate drivers and invalid drivers. It separates the updates that require you to restart your computer so that they are easier to distinguish. You can download Snappy Driver Installer from here.
Additionally, we suggest you to check that there are no duplicate audio drivers installed. Expand the "Sound, video and game controllers" section and check if there are any duplicate audio driver entries. If there are duplicate entries, right-click one of them and select "Disable" from the contextual menu. Repeat for other duplicates.
BIOS (Basic Input Output System) is software 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 version for the motherboard. There should be a manual describing how to update the BIOS - ensure that you read this carefully. Bear in mind that updating the BIOS is a procedure for advanced users, and if not performed properly, can cause permanent hardware damage. If you do not know how to update the BIOS, find an expert to avoid damage to your computer.
Turn Off Fast Startup
Turning off the Fast Startup feature could prevent your computer from shutting down unexpectedly and receiving Kernel-Power critical errors. Fast startup is a feature on Windows 10 (and also Windows 8) that provides a faster boot time when starting up your computer. It is a useful feature and one that most people use without knowing, however, some people disable it immediately when they receive a new computer with the Windows operating system. With the fast startup feature enabled, shutting down your computer might seem like you are completely shutting it down, but this is not entirely true, since it moves into a state between hibernation and shutdown. Leaving fast startup enabled should not harm your PC, since it is a Windows feature, but it could cause this problem. To disable Fast Startup, go to Search and type "power". Click on the "Choose power plan" result to open it.
In the Power Options window, click "Choose what the power button do".
Click on "Change settings that are currently unavailable" and then uncheck the "Turn on fast startup (recommended)" option if it is enabled. Click "Save changes" to save the changes made, restart your computer, and check if the unexpected shutdown problems are resolved.
The Kernel-Power critical error is usually power-related, and indicate something wrong with the computer's PSU (Power Supply Unit). Oxidation on the back of the PSU switch might be the cause. In this case, contact a technician to check the PSU - replacing it could solve the problem.
Another possible reason for this critical error is overheating. Computer usually shut down when the temperature is too high. You can download the SpeedFan program, which monitors temperatures and checks if the hardware is overheating when your computer is turned on.
It is also possible that the RAM chip is not connected properly or the slot (or chip) is dusty. If you know how to detach and replace RAM, we recommend that you try this. Remove the RAM chip, clear any dust/dirt, and replace it. Do not do this when your computer is turned on or connected to a power source. When you have finished, reconnect your computer to the power supply and turn it on. Check if you still receive the Kernel-Power errors.
Check that all wires are connected properly (inside and outside the computer box), and check if the power connectors are properly connected for both GPU and main board (motherboard). Also, remove the CPU and reseat it (if you have these expertise).
We hope that this guide was useful and helped to fix the Kernel-Power critical error (ID 41). If none of the methods mentioned above solved the problem, it might be hardware-related issue and you should contact a computer technician to check the system.
