What is Kernel Power 41, Category 63?

The Kernel Power 41 event signals an unexpected system shutdown. It can happen for several reasons:

  • The system suddenly shuts down or restarts without properly shutting down.
  • Power interruptions, overheating, or issues with the power supply unit (PSU).
  • Problems with drivers or the system configuration.

The Category 63 code in the Windows event log often points to power-related issues or failures of specific components.

Step-by-Step Guide to Fixing the Error

1. Check the Power Supply

One of the most common causes of the Kernel Power 41 error is an insufficient or faulty power supply. Ensure that your PSU is functioning properly and provides enough power for your system’s requirements.

2. Update Drivers and BIOS Firmware

Outdated drivers, especially for the graphics card, can cause errors. Update all drivers to the latest versions, either through Device Manager or by visiting the manufacturer’s website. Also, check for BIOS updates on your motherboard manufacturer’s site.

3. Disable Fast Startup

The fast startup feature in Windows 10 can sometimes cause instability and trigger the Kernel Power 41 error. To disable fast startup:

  1. Open the Control Panel and go to Power Options.
  2. Select Choose what the power buttons do.
  3. Click on Change settings that are currently unavailable.
  4. Uncheck the option Turn on fast startup.
  5. Save the changes and restart your computer.

4. Check for Overheating Issues

Overheating can lead to sudden shutdowns. Check the temperature of your CPU and graphics card. If overheating is an issue, make sure that fans are working, and that the system has good airflow. Clean out any dust and ensure proper ventilation.

5. Test Your RAM

Faulty RAM can also cause this error. Use the built-in Windows Memory Diagnostic tool to check for memory issues:

  1. Press Win + R, type mdsched.exe, and press Enter.
  2. Select Restart now and check for problems.
  3. After restarting, the system will check your RAM and display the results.

6. Scan for Disk Errors

Run the chkdsk command to scan for disk errors:

chkdsk /f /r

Execute this command in Command Prompt with administrator privileges and follow the instructions.
