Hello. I have been playing Halo and I noticed that the game started stuttering and lagging. I checked the Event Viewer and found an Event ID 55 (Kernel-Processor-Power) error. The issue does not seem to go away. How do I fix this?
Event ID 55 is an error message that may appear in the System log in Windows Event Viewer. It indicates that the Kernel-Processor-Power event has occurred. This event is related to the power management of the processor on your computer. The Kernel-Processor-Power event is generated when the system experiences an issue with the power management of the processor.
This could be caused by a variety of factors, including hardware issues, driver issues, or problems with the power settings on your computer. You may want to try troubleshooting the issue by checking for hardware issues, updating your drivers, or adjusting your power settings.
If you are unable to resolve the issue on your own, there is a possibility that there is an error with the processor itself.
