Question PC randomly restarts while gaming after swapping my motherboard, CPU and PSU

[Gaff1]

Hello everyone,

I'm encountering a frustrating issue with my PC and I'm hoping someone can help me troubleshoot. A few weeks ago, I swapped my CPU, motherboard, and PSU, and since then, I've been getting constant blue screens with the error code WHEA_UNCORRECTABLE_ERROR. The issue started happening even when I was just on the desktop, but it was much more frequent when I played games.

What I've Tried:​

1. Disabled PBO in BIOS: This stopped about 99% of the blue screens. The crashes are now much less frequent, but I still get them in VR.
2. Swapping RAM: I tried using different RAM sticks, but the crashes still occurred, so I don’t think it’s a ram issue.

Current Situation:​

• Now, the system only crashes when I'm in VR. It typically happens a few minutes into the game, and instead of showing the blue screen, the PC just restarts. In the Event Viewer, I get the WHEA error logs, but I’m not sure if I'm just not seeing the blue screen anymore because the PC restarts so quickly. It's possible that the blue screen appears only for a split second before the system restarts.
• Event Viewer Error: The WHEA error shows up with the following details:
  • Reported by component: Processor Core
  • Error Source: Machine Check Exception
  • Error Type: Bus/Interconnect Error
  • Processor APIC ID: 10 (but this number changes with each blue screen)

What I Suspect:​

• CPU Overheating: Currently I only have a 120mm AIO, and I'm starting to wonder if the CPU might be overheating, especially since it blue screens consistently while VR (which is quite demanding). However, I'm not sure if overheating would specifically cause a WHEA_UNCORRECTABLE_ERROR, or if it would just cause thermal throttling and make the game lag.

System Specs:​

• CPU: Ryzen 9 5900x
• Motherboard: ASRock X570 Steel Legend
• PSU: 850W Thermaltake Smart Pro RGB
• RAM: Currently 1 stick of 32gb 3200mhz, but I also tried with 4 sticks of 8gb 2666mhz
• Cooling: 120mm AIO (updated check the end)
• GPU: Gigabyte Radeon RX 6600 8gb
• OS: Windows 10

Alright, need to update some stuff​

• I've upgraded my AIO for a 360mm one

The pc doesn't blue screen anymore, it just suddenly restarts when I'm gaming, but what is weird is that it no longer gives the "WHEA-Logger" error on event viewer, just "Kernel-Power"

• Could it be a failing PSU?

Here is a screenshot of event viewer, the most recent one was today at 9:50 PM but the last WHEA-Logger was yesterday at 11:44 PM
(every AM its actually PM, the clock was wrong, just the last 2 that correctly says PM, because thats when I fixed)

Did you swap out the components and use the existing win10 OS after upgrade, or did you do a fresh install after upgrade?

originally i did, but now im on a fresh install

A 120mm aio is small for a 5900x imo. When I had one I was using a 240mm aio with it.

 

[Gaff1]

i know a 120mm aio is small for my cpu, but would overheating really cause a blue screen? shouldn't it just thermal throttle and make the game lag.
i dont wanna buy one just for it to not fix the issue

Try these utilities to see detailed info including temps etc. Have it running in the background while vr is running and check the cpu temps.

i thought about using cpu-z to log to a txt since the pc restarts, but right now its too much work to setup my vr headset, get in game and play just for it to crash, i have to be actively playing the game, because if take the headset off it goes into sleep mode and the game "stops processing" vr.

i bought a 360mm aio, just waiting for it to arrive, gonna install it and if it doesn't fix the issue i'll come back

 

[Gaff1]

new aio arrived today, installed and it still restarted with the same error, this time i wasn't even in VR

Have you looked at the temps and hardware using the software from my last post??

not the ones you suggested, im using hwmonitor, temps are better, not hitting 90+ C anymore, but still fluctuates a lot
the highest i saw was 78 C

 

[KingLoki]

90+ is getting a little high. Whats it at idle with nothing running?

you understood that wrong, i said its not hitting 90+ like it was before, now the max is 78 under load, but the pc still "blue screens"

R U overclocking your Ryzen or your RAM?

no, neither, i even disabled amd pbo

Have you tried testing your RAM? That would be the 1st thing I would try. I usually use prime95 w/the large FFTs test.

as i said in the first post, I have tried using different RAM stick

 

[80251]

Swapping RAM sticks isn't the same as TESTING those RAM sticks. It could be you have a marginal IMC in your 5900x. Are the memory sticks on the QVL list for your motherboard? Are there any 32GB sticks of memory on the QVL at all?

where do i check that?

 

[80251]

Go to asrock's website and look up your motherboard there, the information page will have the QVL list for all RAM Asrock tested w/your motherboard. Good luck.

alright, need to update some stuff because the original post is no longer 100% of what is happening.
also updated the original

the pc doesn't blue screen anymore, it just suddenly restarts when i'm gaming, but what is weird is that it no longer gives the "whea-logger" error on event viewer, just "kernel-power"

could it be a failing PSU?
