New PC shutdowns from "Kernel-Power (Event 41)"

I finished building a new PC a few days ago. It randomly shuts down without BSOD. Event viewer:
So far it has not happened while I was sitting at the PC. I come back to use it and it is powered off. I have not been doing anything while away. PC was just idle with some apps open.

Event viewer does not record a stop error reason, which is scenario 3 from this link: https://docs.microsoft.com/en-us/windows/client-management/troubleshoot-event-id-41-restart which says "something prevents Windows from generating error codes or from writing error codes to disk. Something might block write access to the disk (as in the case of an unresponsive computer) or the computer might shut down too quickly to write the error codes or even detect an error."

Here are the components I used:
  • MSI Tomahawk x570
  • Ryzen 5900x
  • Enermax Revolution D.F. 850W
  • HyperX Fury Black 3200MHz 64GB (2x32GB)
  • RTX 3060 Ti
  • Corsair H150i Pro XT
  • WD SN730 NVMe (Windows install)
  • Samsung 970 EVO Plus (Games install)

What I have tried so far:
  • Disabled fast startup in Windows
  • Remove XMP from RAM and go back to default profile (not using any other overclocking)
  • Re-seating RAM and graphic card
  • Tested with my old 980 Ti card
  • Tried re-creating the error with:
    • Cinebench single- and multi-core test
    • OCCT test large data set - one hour
    • OCCT RAM test - one hour
    • OCCT Power test - one hour
None of the tests resulted in the error, so I have not seen it happen "live" yet. I still have my old PC running from the same power socket, so it should not be anything external with the power either.

From the tests I would think it could be something with the motherboard, power supply or cpu? Or the BIOS update to support Ryzen 5000 series could have issues? I am not sure how to further test a hardware problem like this, except RMA components that could be an issue. Because of the current hardware supply issues I had to order parts from many different shops, so it would be good to narrow down which part could be at fault.

Had same issues as you with a similar build. What fixed it (mostly) for me was to disable XMP and manually set my RAM to FCLK 1600Mhz and force DDR4-3200 specs on my 3600 speed ram. I am using a beta bios 7C35v1D2. I had disabled PBO and CPB, but since enabled it and my PC is now stable. Also manually set some voltages VCore to 1.375V and VSoc to 1.125V. These are CPU voltages (not chipset). I am still having some reboot issues with ntfs.sys, but nowhere near as much. Hopefully the next BIOS release will address most of these issues. Good luck.

Your memory could be a problem.
You should try two certified matched pairs of 16gb single rank RAM installed dual channel.
I have two matched pairs, one in red and the other in black, so I don't mix them up.
The pattern goes: RBRB or BRBR.

I tried with a different PSU, but I get the same error. Excluded that part from RMA at least.

Setting the RAM to default SPD (2400 MHz) seems to reduce the number of errors, but it still happens sometimes. Which makes me think it is a BIOS issue. I am still within the return period, so I could get a different motherboard. Or is this a general problem with all AM4 motherboards for zen3 and something AMD needs to fix?

The memory I bought (HX432C16FB3K2/64) is on the QVL list for x570 Tomahawk (https://www.msi.com/Motherboard/support/MAG-X570-TOMAHAWK-WIFI#support-mem-21), so it should work. It is installed in A2 and B2 slots (only 2 sticks as each is 32gb). But it could of course be faulty. I am not sure about buying another set of RAM to test with, but maybe that is the only way to truly test if the RAM is ok.

Well, a quick look in Asus and Gigabyte forums shows that all new AMD based BIOS versions seem to have the same RAM issues. Looks like an Agesa issue to me...

Edit: There is a Reddit thread about current faulty Agesa versions: https://www.reddit.com/r/Amd/comments/kfm683

Have you tried all four RAM configurations?
XXMM or MMXX or MXMX or XMXM

Other than memory, it could be the power hungry 200w video card that's pulling the system down.
Have you tested the Ground bonding of your case?

I have am have the same problem with my x570 tomahawk wifi. But I am still using Ryzen 7 2700x, 32gb g.skill ram(qvl), Radeon rx 580 8gb, 750w 80plus gold power supply, xpg sx8200 pro 512gb nvme. I have no idea why.

Have you tried disabling XMP ? Worked for me. RAM access seems to have been messed up in Agesa.

Having same issues with a ryzen 5 3600 and the x570 tomahawk wifi since day 1, always kernel-power 41 (63). I can play any games for hours but only random BSOD's at idle, or in chrome/youtube, light workloads.
I know the cpu and the others parts work fine because are from an old build, tried everything, another cpu (2600 works fine), another psu, updating bios, etc. The system only works well if I turn off PBO and CPB and that is not ideal for me. I suspect it's a bios/energy related problem because the 2600 works really well, and never push over 1.2v and noticed 3600 uses 1 to 1.4+v, or maybe I got a broken MB. Sorry I'm not an overclocker, or an expert, I'm just a frustrated normal user.
And sorry again for my poor English it's not my main language.

Try this:
It could be a windows Device profile history issue.
Go into device manager and use option "show hidden devices" under View, then expand each key (except Bluetooth) and delete/uninstall all the old ghost profiles (grayed out), if any, then reboot.

Check this; X570 Tomahawk wifi + Ryzen 7 5800x workaround

Hope it helps!

I figured out my kernel power 41 error. For some reason the new Ryzen power plan that came with the chipset drivers installer that AMD reseased earlier this month didn't play well with my Ryzen 7 2700x and my x570 tomahawk wifi. Completely uninstall the chipset drivers with the Ryzen power plan. Boot into safe mode and removed anything that was related to the chipset/power plan including registry entries. Reboot back to the windows. Installed the pcie inf, gpio2 inf, smbus info one at a time. Now my windows 10 is running awesome.

Mine still crashing, only works stable if I turn off PBO and CBP. I suppose is better than nothing :(

Did you ever figure it out??? Search for bluescreenview.exe on google. It lets you see what is in the memory.dmp file. Hopefully this helps.

I downloaded it and notice that 3 files are causing the bsod's: ntoskrnl.exe Npfs.SYS win32kbase.sys
i googled but only found generic solutions that i already tried.
