How to fix a Windows Kernel power error in 5 easy steps

Does your Windows computer shut down without warning? Here’s how you can fix Kernel-Power Event ID 41 and stop Windows from crashing.

Does your Windows computer shut down without warning? Or does it crash every time you attempt to wake it from Sleep? Your computer might have a power supply fault, causing it to crash without warning. The issue, known as a Kernel-Power error, seemingly appears for no reason, yet is a critical system issue. Here’s how to fix Kernel-Power Event ID 41 and stop your computer from crashing.

What Is a Kernel-Power Critical Error?

The Kernel-Power critical error is a system error that causes your system to crash. The error can trigger under a range of circumstances, though all relate to power issues or system reboots without a clean shutdown. However, the Kernel-Power 41 issue doesn’t always indicate a power supply issue but can also indicate an issue with your system hardware, causing a power fault and, in turn, your system to crash.

The Kernel-Power critical error is typically associated with Event ID 41. Furthermore, Kernel-Power Event ID 41 is accompanied by the keywords (70368744177664),(2), which you can use to pinpoint your bug troubleshooting.

So, what causes Kernel-Power error 41? While it is a common shutdown error code, there are several common causes with easy fixes:

  1. Update Windows 10 or Windows 11
  2. Disable Windows fast startup
  3. Reseat your RAM and graphics card
  4. Test for a faulty PSU
  5. Run CHKDSK and SFC

Let’s take these fixes step by step and solve the Windows Kernel-Power error. Please note that this article deals exclusively with the Kernel-Power 41 error. However, we’ve also covered fixes for the unexpected kernel mode trap error, some of which differ from the fixes for the Kernel-Power error.
