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

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"

Edit: Nevermind, WHEA errors are back
  • 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)

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
 
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??
Click to expand...
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

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
 
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?
 
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?

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

You can get kernel power errors in Windows 10 when your system reboots without being properly shutdown (i.e. the system restarts you experienced) -- in this case no WHEA errors are thrown because the system restarted and the error couldn't be recovered from. WHEA errors are only thrown when the system can recover from them.
A PSU can cause system resets if it triggers over voltage protection or over current protection.
You should state what kind of PSU you have.
I still think it's your RAM or the IMC on your 5900x may be marginal, I'd suggest running prime95 w/largeFFTs
to test your RAM and CPU IMC.

i have a 850W PSU from Thermaltake, i suspect it might be the psu because i bought it off a friend and it was really dirty, so i think it was running really poorly and that decreased its lifespan

but i will try prime95, but for how long should i run it?

when playing vr my pc restarts after only a few minutes in game, i ran prime95 for 30 minutes no errors and it didn't restart.

You weren't running the "large FFTs" test though. The Large FFTs test "stresses memory controller and RAM". A half hour isn't really much of a test either. Several hours would be more conclusive. I test for at least 3 to 4 hours.
As KingLoki suggested try running HWiNFO64 and getting a screen capture of what it reports for your voltages, CPU speeds, FCLK, memory clocks, CPU/DRAM voltages then posting it here. You might have to take two screen caps to get everything.
