System Specifications


  • Motherboard: ASUS Sabertooth Z97 Mark 1
    CPU: Intel Core i7 4790K / Noctua NH-D15
    RAM: GSKILL F3-12800CL9-4GBXL (X2)
    GPU: Sapphire Radeon R9 380 Nitro (Driver Crimson 18.8.1)
    PSU: XFX XTR-550w
    OS: Microsoft Windows 10 Professional (x64) Build 17134.228 (1803/RS4)
    HDD: KINGSTON SV300S37A120G + SAMSUNG HD103SJ


What happens is that sometimes (as in there are days I can go all day without the issue), my computer just shutdown and restart itself, generating an Event 41, Kernel Power on event viewer with BugCheckCode 0. For now it happens mostly during gaming and began to happen very recently during some sessions of Monster hunter World. With a bit of research I've come to a few theories:


Overheat

Not the case. I've been monitoring it and my CPU never goes above 62C @100%, my GPU never above 72C @ 100% and overall motherboard temperatures doesn't go far than 40C. A sensor I've put inside my PSU shows it doesn't go above 35C.

PSU

Not the case. I've switched PSU's to a Corsair RM550x and the problem continues.

RAM

Ran Memtest64 for 12 hours straight and nothing! No shutdown or errors.


For now, I'm out of ideas. I've been thinking about reinstalling the OS, but I doubt it'll solve anything? Or will it?

Please Help.

When you update the driver, you should use the DDU. Usually, like your circumstance (BSOD), which will be caused by driver, hardwrae like RAM, MB, GPU etc.

Event 41, Kernel Power will be caused by overheat, PSU ( can't handle the GPU), GPU, etc. because when the computer is shut down, or it restarts unexpectedly, then you can get the Event 41, Kernel Power error.

Thanks for the answer, didn't knew about this, but I guess it's not that. I have about 47GB free on that SSD, since I only have the SO, some applications and 1 game, this case Monster Hunter World.

Because you said no overheat for cpu/gpu, RAM are fine.

But how about the GPU, do you test it in other PC? or use software, like MSI afterburner to increase the voltage little bit, or underclock the r9 380, that will help run the GPU more stable. Also how the GPU driver too, use DDU uninstall the driver in safe mode, that reinstall the driver again.

Makes sense, it began to happen after I've installled the latest AMD update, even tho I've never considered a driver to shutdown a PC without a BSOD. I'll test a clean driver instalation and perhaps a driver downgrade. Sadly I don't have another PC with compatible hardware for the GPU. Is there really a chance for a GPU to cause this issue?

Turns out it may be the PSU as the one I've borrowed is apparently with the same symptoms as mine. With that said, I've picked this up as solution and will open a new thread with advice for a new PSU. Thank you.
