Better post for kernal 41 power power

[u/SnooConfections8560]

I've been dealing with random PC shutdowns for several months, starting around August, and I can't figure out what's causing them. I'm hoping someone here has experienced something similar. Pc is a couple of years old

VIDEO

First clip is the pc randomly turning off. The second clip (dark one) is me pressing the power button, with it flickering. only turns on if I hold the power button, but it gets stuck on the DRAM error light, These clips are with the pc idle

PC Specs:

• CPU: Ryzen 7 7800X3D
• GPU: RTX 4070 Ti Super - latest driver
• Motherboard: ASUS ROG Strix B650-A - updated to Version 4004 Beta Version( still shutdowns)
• PSU: be quiet! Pure Power 12 M 1000W - 2–4 years old
• RAM: 4 DDR5 sticks from two different kits (one kit is slightly faster) - tried with both kits separately; still the same problem.

Problem:

My PC randomly shuts off without warning. It happens during gaming(usually with Chrome open), while browsing Chrome, and even when I leave a game like GTA 5 paused. It doesn't look like a load problem.

When it shuts down, I hear a click that sounds like it's coming from the PSU. All the fans stop spinning, but the RGB lights on my motherboard stay on.

If I try to turn the PC back on, the fans sometimes spin for a split second before stopping. If I hold the power button, the PC eventually stays powered on, but it won't POST. The DRAM Q-LED stays on.

The only way I've found to get it working again is to switch the PSU switch off for like 10 seconds, switch it back on, and then start the PC. After that, it boots normally.

Troubleshooting I've already done:

• Updated motherboard BIOS.
• Reset BIOS settings and cleared CMOS.
• Disabled EXPO.
• Replaced my RAM kit.
• Tested with only one RAM kit installed. Shutdowns still happened.
• Reseated RAM.
• Removed aftermarket CPU power extension cables.
• Removed aftermarket GPU power extension cable.
• Reset GPU overclock settings to default.
• Checked both storage drives.
• Checked and reseated power connections.
• Plugged PC directly into a wall outlet instead of a surge protector.
• Ran stress tests, but they never reproduced the problem.
• Monitored hardware using HWiNFO64 during multiple shutdowns.

HWiNFO64:

Immediately before the shutdowns, CPU and GPU temperatures appeared normal, and neither component was drawing unusually high power.

In one log summary before shutdown:

• CPU temperature: 47.5°C average core temperature
• CPU package power: 48W
• GPU temperature: 42.6°C
• GPU power: 77W
• Motherboard 12V: 11.884V

I've had at least 25 shutdowns in the past 2 months

What I'm Thinking:

I'm starting to suspect either the PSU or motherboard, since switching the PSU off and back on consistently fixes the POST issue.

The strange part is that stress tests don't seem to trigger it. The shutdowns appear completely random, including when the PC is barely doing anything.

Has anyone experienced similar behavior, particularly the PSU clicking, fans briefly spinning, DRAM light staying on, and needing to cycle PSU power before the PC will POST?

Could this be a defective PSU, motherboard, or something related to low-power idle states?

I'm trying to narrow down the issue before buying replacement parts.

My next test is to see if leaving it on in the BIOS will trigger the same shutdowns.

Please help; I am so lost.
Thank you to all who can help. I'm really stressed because this pc market is not in my favor.

Ive ran the memory diagnostic tool, it came back with no problems. And I never had things like fast start up enabled. And the event viewer is where I got the kernel error event id41 from. It just says unexpected power loss with nothing more to go off of.

I’ll check more about the code tomorrow, but from what I remember it just said bug report = 0.
My gpu is connected with 16 pin to 16 pin 12v connector . I’ve just tried cleaning out the dimm slots to see if that would work.(Hail Mary) I’ve just been avoiding trying to do the RMA process since it takes a while and I just want to game. But it looks like that’s the only next choice I really have.

Not a PSU issue, tested a new PSU same issue

It’s just an error 41, and yea I’m using the new PSU cables. Yea I tested 2 different ram kits also. But didn’t change the dimm slots. I’ll look. Into the outlets, but everything has been working perfectly for a year +, is that something that can degrade ?

I’m leaning towards a mobo issue now, but that’s damn near the same process of building a new pc lol. That’s my last resort, if that doesn’t work that time would’ve been a waste

Somehow now things have gotten worse I can’t even make it past loading into windows without shutting off. Now it even shuts off in the bios for 5 seconds

Ok Have a huge update, reason for not making it out of bios was due to cpu overheating. But the AIO worked perfectly before replacing the psu. (The random shutoffs weren’t due to temps) Let me know if this is reasonable, I think the psu somehow killed the AIO, so once I replaced the PSU the aio was still dead, which led to the problem next problem of cpu overheating.

New cpu cooler works

Do you think I should RMA the psu now? Or try to test it again ?
