How To Fix Kernel Power 41 63 Error in Windows 10/11

Experiencing a sudden shutdown or restart on your Windows 10 or Windows 11 PC can be alarming. When you check the Event Viewer to understand what happened, you might encounter an event logged as “Kernel Power 41 (63).” This cryptic message leaves many users puzzled about its meaning, causes, and, most importantly, how to resolve it.

This article demystifies the Kernel Power 41 (63) error, explores its potential causes, and offers comprehensive methods to fix it, ensuring your system’s stability and performance.

Kernel Power 41 63

What Does Kernel Power 41 (63) Mean?

The Kernel Power event ID 41 (63) is a non-specific error logged when your computer restarts unexpectedly without a proper shutdown. This log is a symptom rather than a diagnosis, indicating that the system stopped responding, crashed, or lost power unexpectedly.

The “(63)” qualifier specifies that the event occurred during a system session where the shutdown process was incomplete.

Causes of the Kernel Power 41 (63) Error

The Kernel Power 41 (63) error can stem from various sources, making it a challenging issue to pinpoint. Common causes include:

  • Power Supply Issues: Inadequate or failing power supply units (PSUs) can’t provide enough power, especially under load.
  • Overheating Components: Overheated CPU, GPU, or other components can lead to system instability and shutdowns.
  • Faulty Hardware: Defective memory, motherboard, or other hardware components can cause sudden restarts.
  • Driver Conflicts or Outdated Firmware: Outdated or corrupt drivers and firmware may lead to incompatibilities and system crashes.
  • Software Issues: Certain applications or operating system errors can also trigger this event.

How to Fix Kernel Power 41 (63) Error

Inspect Power Supply and Cables

Ensure your PSU is adequate for your system’s needs and that all power cables are securely connected. Consider using a PSU calculator online to verify if your PSU provides sufficient power.

Check for Overheating

Monitor your system’s temperature using software tools. Ensure that cooling systems (fans, heatsinks, liquid cooling) are functioning correctly and that there’s no dust buildup obstructing airflow.

Test Hardware Components

Utilize built-in diagnostic tools like Windows Memory Diagnostic for RAM or manufacturer-specific software for testing other components like the CPU and GPU. Consider replacing any faulty hardware identified during these tests.

Update Drivers and Firmware

Ensure all device drivers and system firmware are up to date. This includes GPU drivers, motherboard BIOS, and any peripheral firmware. Manufacturer websites often provide the latest versions.

Conduct a Clean Boot

Perform a clean boot to identify if background applications or services are causing the issue. This involves starting Windows with a minimal set of drivers and startup programs.

Restore or Reset Windows

If the problem persists, consider using System Restore to revert your computer to a previous state before the error began occurring. Alternatively, resetting Windows 10/11 can provide a fresh start, though it’s a more drastic option.

Replace the Power Supply Unit (PSU)

If diagnostics suggest the PSU might be inadequate or failing, replacing it with a new one that meets or exceeds your system’s power requirements could resolve the Kernel Power 41 (63) error.

Is a Higher Wattage PSU Better for Preventing Kernel Power Errors?

While having a PSU that provides more power than currently needed can offer headroom for future upgrades, it’s not a guaranteed fix for the Kernel Power 41 (63) error. The key is to ensure the PSU is of high quality, reliable, and appropriate for your system’s power consumption.

Advanced Diagnostic Tools

Leveraging Windows’ built-in or third-party diagnostic tools can provide deeper insights into system health and potential points of failure. Tools like the Reliability Monitor offer a timeline of system events and errors, helping identify patterns that might correlate with Kernel Power 41 (63) occurrences.

Additionally, stress testing utilities for CPU, GPU, and RAM, such as Prime95, FurMark, and MemTest86, can simulate high-load scenarios to test the stability of these components under stress.

System Event Logs

The Event Viewer in Windows is an invaluable resource for troubleshooting the Kernel Power 41 (63) error. By examining the logs around the time of the unexpected shutdown, users can often find additional error codes or warnings that provide clues to the underlying cause.

Paying close attention to critical and error-level events in the System and Application logs can highlight driver failures, application crashes, or hardware malfunctions that precede the shutdown event.

Power Settings and Plan Adjustments

Windows power settings can influence system behavior in ways that might contribute to unexpected shutdowns. Adjusting these settings to ensure a balanced performance, especially regarding sleep and hibernation modes, can mitigate issues causing the Kernel Power error.

For high-performance users, such as gamers or professionals running intensive applications, customizing the power plan to prevent sleep and adjusting processor power management to 100% can ensure maximum stability.

BIOS/UEFI Settings and Overclocking

Incorrect BIOS/UEFI settings or aggressive overclocking can also lead to system instability manifesting as Kernel Power 41 (63) errors. Restoring BIOS/UEFI settings to default or ensuring they’re configured correctly for your hardware is crucial.

If the system is overclocked, consider reverting to stock speeds or employing more conservative overclocking settings, as instability often arises from pushing components beyond their stable operating limits.

External Factors and Environmental Conditions

External factors, such as fluctuations in the power supply from the outlet or power strip, can cause unexpected shutdowns. Using a Uninterruptible Power Supply (UPS) can provide a stable power source and protect against surges that might trigger Kernel Power errors.

Additionally, ensuring the computer is in a well-ventilated area and not exposed to excessive heat or humidity can prevent environmental conditions from impacting system stability.

When to Seek Professional Help

If after exhaustive troubleshooting the Kernel Power 41 (63) error persists, it might be time to consult with a professional.

Computer repair services or technical support from your computer’s manufacturer can offer advanced diagnostics and repairs that may be beyond the scope of typical user interventions. In cases where hardware failure is suspected, professional assessment can determine the exact cause and recommend appropriate solutions.


The Kernel Power 41 (63) error in Windows 10/11 is a sign that your computer experienced an unexpected shutdown. While the causes vary widely, from power supply issues to hardware failures, systematically troubleshooting each potential source can help you pinpoint and resolve the underlying issue.

Regular system maintenance, including cleaning, updating drivers and firmware, and monitoring system health, can prevent many such errors and contribute to a stable, efficient computing environment.
