How can I fix the Kernel Power 41 error on Windows 10?

In this article

Before getting into the actual tweaks, let’s go through some simple checks that might fix the problem quickly:

• Check for any drivers that display a yellow exclamation mark in Device Manager. Just like with the Kernel Security Check Failure error, it’s recommended to make sure that your drivers are OK, and the exclamation mark to their right signals a possible problem.
• Make sure that your Windows OS is updated.
• Restart your PC. The system may recover without any intervention whatsoever.
• Check your hardware for any damage and look if the fans inside the PC are working properly. This error may be triggered by hardware failure or overheating. If this is the case, stop your machine and make the necessary repairs ASAP.

If you crosschecked the critical steps above, let’s fix this problem by using the solutions below.

1. Update your drivers

1. Right-click the Start button and select Device Manager.
2. Expand the sections one by one, and look if any of the drivers have an exclamation mark to their right.
3. Right-click the driver and select Update driver.
4. In the next window choose the Search automatically for drivers option.
5. The system will look for any updates and install it.
6. If the problem still persists, instead of updating the driver in step 3, select Uninstall device.
7. Reboot your PC and the system will detect the device and install a generic driver for it.
8. If that doesn’t work either, go to the manufacturer’s website and download the driver for your OS.
9. Perform this solution especially for the audio and graphics drivers as they are the most prone to producing this error.

The kernel-power 41 (63) Windows 10 error is sometimes caused by outdated drivers, and if you want to fix it, make sure that you have the latest drivers installed.

If you do not have the necessary computer skills to update/fix the drivers manually, we strongly suggest doing it automatically by using a third-party tool.

2. Disable duplicate audio drivers

1. Right-click the Start button and choose Device Manager from the menu.
2. When Device Manager opens, locate your audio drivers in the Sound, video and game controllers section.

We already mentioned that Kernel Power 41 errors can be caused by your audio driver, so make sure that you check Device Manager for any duplicate driver entries.

Even if you don’t have duplicate audio drivers, you can try disabling one of the audio drivers that you have on the list.

Users have reported that the issue was resolved after disabling ATI High Definition Audio Device from Device Manager.

Even if you don’t have ATI High Definition Audio Device installed, you can try disabling any audio device that isn’t High Definition Audio Device.

4. Increase the CPU core voltage

One of the problems causing the Kernel Power Error 41 is that the CPU is not getting enough power from the system.

Hence, a viable solution is to increase the CPU core voltage. One way to do that is to look for CPU voltage settings in BIOS.

However, not all BIOS software have this option so a more simple solution is to use a CPU overclocking dedicated app.

For example, in MSI Afterburner, you just need to access the Settings menu and adjust the voltage of the
