Apologies in advance if this is not the right section of the forum, I know this is not really a BSOD but it seemed the most relevant section nonetheless.
Been playing D4 since launch day without any issues, then a couple nights back while running a dungeon my PC suddenly turned off and restarted itself.
At that point I went into the BIOS to check if any overheating had occurred, but the temps in the system were all averaging 60 °C.
Then I tried logging back into Windows, but as soon as I entered my password the pc would turn off (hard turn off, not a soft reboot) and turn itself on again, rinse and repeat.
I spent the night trying to troubleshoot but in the end I had to do a full recovery through the Windows troubleshooting options that you can access at boot time (both startup repair and roll back to a system restore point failed).
After that I quickly reconfigured the bare bones apps I run on Windows and left the pc on for the whole night and day after.
Yesterday, as soon as I tried starting Diablo again (think as soon as the blizzard logo comes up) the pc AGAIN turned completely off and then back on again. Same deal as the day before, no windows troubleshooting option works and as soon as I try logging in it turns off and on again.
After I went through the recovery process again and tried to test Diablo, the PC quickly turned off and this time the crash loop got extremely more severe, where the system would have power for ~1s before shutting itself off again.
During the day I tried a bunch of things, none of which worked, and I resigned myself to the idea that my CPU was dead (seeing that the debug LED on the motherboard for the CPU came on while the system had power). I started the RMA process with Intel to get it swapped, but then I just tried resetting the CMOS as a last attempt before pulling the CPU out and lo and behold the system came to life again.
After that I updated my BIOS to the latest version and set everything up again, tested first without a GPU installed and ran Prime 95 (no problems)
I then attached the GPU and ran Furmark, again no problem.
I reinstalled Diablo 4, and as soon as I got to the character screen the PC turned off on its own once again.
At the very least this time I'm not stuck in a crash loop and was able to get to the Event viewer in Windows, and this is what I found:
Event with ID 41, Kernel-Power, at level Critical:
Code:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
Right before that one there is another Kernel-Power event (at level informational) with ID 125, with the following contents:
Code:
ACPI thermal zone \_TZ.TZ00 has been enumerated.
_PSV = 0K
_TC1 = 0
_TC2 = 0
_TSP = 0ms
_AC0 = 353K
_AC1 = 328K
_AC2 = 323K
_AC3 = 318K
_AC4 = 313K
_AC5 = 0K
_AC6 = 0K
_AC7 = 0K
_AC8 = 0K
_AC9 = 0K
_CRT = 378K
_HOT = 0K
minimum throttle = 0
_CR3 = 0K
I can guess this is related to temperatures, and all those 0s are kinda worrying me, but I cannot find anything that explains in detail what these values are supposed to be. I tried googling around and found other people who have their PC shutting off semi-randomly and also find some variation of this event in their Event Viewers, but none of the posts I found have a definitive answer as to what's going on.
Unfortunately there appears to be no minidump in C:\Windows to explore the issue any further (I imagine that's because the system does a hard turn off).
At this point I really don't know what I can do. Should I just go ahead with the RMA? Unfortunately I don't have another compatible mobo/CPU to test a different combination of hardware and single out the CPU being the culprit
