Hi, for a few months (~3) i've had a very stressful issue where my PC will just reboot during games. This can be anywhere from 1 second - 5 hrs into a game. The system is completely stable when not playing games and I usually leave it on overnight, not once has it crashed.
Synthetic stress tests cannot replicate this issue: I can run p95 for days on each setting, memtest86, occt, furmark.
SPECS: r7 3700x, rog strix 5700xt, prime x470, 32gb 2300 ram, cm1000x (1000w) psu, kingston a2000 nvme.
The system doesn't create logs all the time, when it does, only a log in event viewer is visible. this shows
"
A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 7
"
I have tried the following:
PSU: bought a cm650, issue persists.
RAM: played with timings, DOCP (even though none of the ram tests show any instability) to no effect.
CPU: disabled PBO with no effect. bought an aftermarket cooler with no effect.
GPU: updated vbios, tried 10+ diffent gpu driver versions with DDU in between. Tried quiet and normal bios.
HDD: bought a samsung 760evo as os drive, no effect.
mobo: flashed bios with different versions, no effect.
general: updated all drivers, played with power versions, tried windows 2004, 1803, 1903
temps are great: everything at max 70c, except for the GPU hotspot which gets up to 91c when stresstesting for 1h+
Assembled the system a couple times. MOBO is properly attached to case with all standoffs, nothing shorting, no dust.
Any advice would be appreciated. I suspect the CPU is the culprit.
