Windows 10: Kernel Processor Power Event 37 Followed by Crash

I have some experience with fixing my own stuff Windows wise, but as I'm unfamiliar with some of the shenanigans that happen when messing with the kernel, I'd rather ask around first.


I've been having some infrequent crashing issues, which have often been messing with my audio drivers causing me no end to grief, but I've recently replaced that audio driver with what seems to be a more resilient if slightly lower sound quality version that's compatible with the sound card on my laptop. That seems to have fixed the sound driver issue, but the cause of the crashes was clearly not related.


This time, as I was less busy dealing with sounding like a demon robot and getting random bass drops at max volume, I took the time to sort through Event Viewer and noticed that some variation of this warning has been thrown before 3 of the past 5 crashes I've had:


The speed of processor 3 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 23 seconds since the last report.

Do we have any idea what settings I could afford to change- be it in Windows or on the BIOS of the laptop itself- that would fix this issue?

Kernel-Power event id 41. BugcheckCode 0

Hello,

Thank you for writing to Microsoft Community Forums.

In-order to get more clarity on this issue and to assist you with appropriate troubleshooting steps, reply with answers to the below questions:

1. Are you aware of any changes made on your PC, prior to this issue?
   
2. Is this issue specific while playing a particular game?
   
3. Which edition of Windows are you currently using?
   

A Kernel Power Event 41 can occur in the following scenarios.

Scenario 1: The computer restarts, and there is a Stop error BugcheckCode in the event data.

Scenario 2: The computer is shut down by pressing and holding the power button.

Scenario 3: The system randomly restarts and no Stop error BugcheckCode is listed, or the computer is completely unresponsive (hard hang).

I suggest you refer the article on Kernel
Power Event ID 41 and follow the steps for the scenario that is causing this error on your PC.

Additionally, you can refer the article on Windows
Kernel event ID 41 error "The system has rebooted without cleanly shutting down first" in Windows
and check if that helps.
