Crashing System: Hyper-V-Hypervisor with the Event ID 167

Question

My computer is randomly shutting down. Had the problem for the last 4 weeks. I cant workout what triggers it. Sometimes the computer is under load, sometimes its idle with no one using it. Sometimes I can use the computer for hours before it happens, other times it will happen three times in 10mins.

In event viewer the Warning, Hyper-V-Hypervisor with the Event ID 167 seems to consistently prelude the shut down.

"The hypervisor did not enable mitigations for side channel vulnerabilities for virtual machines because HyperThreading is enabled. To enable mitigations for virtual machines, disable HyperThreading." Following that there is an Error and a Critical (Event 41, Kernel-Power).

Running

Processor: 13th Gen Intel(R) Core(TM) i5-13600K (3.50 GHz)

Installed RAM 32.0 GB (31.8 GB usable) 6800 MT/s

System type 64-bit operating system, x64-based processor

Win 11 Pro (OS 26200.8039)

4x SSD

Did a clean windows install yesterday.

Windows Memory Diagnostic reports no errors or faults.

Drivers all reinstalled and up to date.

Minidump reports:

Any help is appreciated.

Hello Scott,

Thanks for sharing a well-detailed issue (your drivers seems to be O.K) but your CPU "don't"

THE ISSUE WITH Event 41 (Kernel-Power)

• The Probable Root Cause of this issue might be your INTEL CPU (Especially with the 13th Gen.)
  "13th gen CPUs had stability problems"
  //
  Although, you can try (Disable XMP / Update your BIOS / Disable “Enhanced Turbo” or “MultiCore Enhancement”)
  //
• Worth Checking: Power Supply + Power Stability + Wall Socket + Power Cables
• To Confirm the root cause: Disable Hyper-V and try using the device,

Open “Turn Windows features on or off”
Uncheck: Hyper-V + Virtual Machine Platform + Windows Hypervisor Platform
(For Testing / few hours)

I do recommend to avoid 13th gen and 14th gen due to the instability issues especially with (K Series)

Regards,
