PC Restarts During Heavy GPU Usage – Kernel Power 41 Error

[jy132]

Hello,


I'm experiencing an issue where my PC automatically restarts during heavy GPU workloads. Specifically, this happens when the GPU board power draws around 280W. I'm doing AI model training, and the same code runs fine using only the CPU. However, when I switch to using the GPU, the system restarts unexpectedly.


After the restart, I consistently see a "Kernel-Power 41 (63) Critical" error in the Windows Event Viewer.


To isolate the issue, I also ran a GPU stress test using FurMark, and the PC restarts there as well—indicating it's not specific to the training code.


Here are some relevant specs:

• CPU: AMD Ryzen 7 9700X 8-Core Processor 3.80 GHz
• GPU: RTX4090
• PSU: 1st Player NGDP Gold 1000W
• OS: Windows 11
• Driver version: 566.24

By the way, I have successfully complete some training code with GPU that consume around 50W GPU power. The PC is working fine when there is no heavy usage of GPU (I also stress tested the CPU alone, and no issue)

I would appreciate any help or suggestions on how to resolve this. Could this be a PSU issue or GPU hardware fault? I've attached a HWiNFO sensor log captured during the workload that causes the restart.


Thank you.

Could this be a PSU issue or GPU hardware fault?

Yes. Or heat.

Your log info is not useful - at least not for me. Knowing the temps of your critical components, and your PSUs voltages are.

Since EVERYTHING inside the computer case depends on good, clean, stable power, you need to ensure you are providing it. So swap in a known good PSU and see what happens.

If still unstable, I would look at swapping in a different graphics card to see if that clears it. If still unstable, you may have a motherboard issue.

Regardless, you need to start by verifying you are providing good power to the card and motherboard and all other components.
