Windows 10: Random crashes/reboots - PSU failling?

First of all, hi and thank you for your help in advance.
This forum's has been an invaluable resource all my life and this is the first time that I actually need to ask for help.

Windows 10 v1909
No hardware or software changes previous to the BSODs.
PSU: Sentey BRP700 (2012)

What happened:

• Playing a game (Hearts of Iron IV), screen flickered/image distorted, Windows rebooted. No BSOD.
• After reboot, Windows logged in fine. Opened internet browser, then, again: black screen, a few seconds later, Windows restarts. No BSOD or error messages.
• After that I was unable to log in in Windows again while my AMD video card driver was installed; only solution was to enter in safe mode, remove AMD driver and let Windows use it's "Basic Display Adapter".

On a personal note, I did face random reboots in the last year or so, but I didn't really pay any attention since well.... Windows sometimes behaves weird and system came back fine from those reboots. Reboots were sporadic, sometimes weeks or months in between. No recognizable reboot pattern.

What I did - #1:

• Reinstalled Windows 10 from zero (formatting including).
• Reinstalled AMD driver: same thing. As soon as the driver installation hit the driver activation sequence, black screen, and a few seconds later the POST *beep*. Computer restarts.
• Only way to access Windows was using the Basic Display Adapter and even so, I did face a couple of random reboots under low stress.

At this point I stopped blaming Windows 10 and started to think there was something hardware related.

What I did - #2:

• Tested different versions of Radeon drivers, from 19.x something up to the latest, removing them with DDU between each install. Same result.
• Tested driver installation removing one memory stick first, then the other. Same result.
• Removed video card and put a backup Geforce GTS 450 instead. Driver installation went fine but system also crashed randomly after some minutes of use, this time with a dif behavior: screen goes black but no automatic reboot. Just stays there forever, and a forced reboot is in order to regain control.
• Even so, after the reboot, I ran FurMark to stress the GPU. To my surprise, system didn't crash. Same thing with stressing the CPU. No crashes, no BSODs, no errors. But as soon as I closed FurMark and opened Opera to access this forum, system crashed. Weird.
• Checked voltages with CPUID and they all seem to be well steady. Voltages in BIOS report normal also.
• Visually inspected all the system -including PSU- for capacitors who might look out or order and -my untrained eye- couldn't find anything obviously wrong.

Here's the V2 log: DESKTOP-CM2UKSV-(2020-04-07_20-36-35).zip - Google Drive

Could the PSU be the having issues? Could it be a motherboard issue?
Thank you!

WHEA_UNCORRECTABLE_ERROR - Random reboots and 0x124 error

Thanks, axe0

How do I explain what steps I took... I ran dm_log_collector.exe but not sure how results were actually acquired/interpreted.

I need to be able to explain steps I took and steps taken to reproduce.

thanks, in advance!

 

Random Reboots

I've had, as the title suggests, random reboots for the length of the time since I've built my computer (2 years roughly) and they're completely inexplicable.

It happens under no load, high load, watching movies, listening to music, playing games, browsing the web, sitting by itself in the room when the my sleeping monitor is even saying WTF?!

There aren't any Events to view other than the usual 0xC*D event when the service just shrugs at me.

Any thoughts or suggestions? Maybe someone has had the same problem before and it was just a loose molex connection? I'm baffled.

 

Reboots/Crashes while Gaming

Hello,

I have random crashes while playing games. Its the same problem as in this thread Random-ish reboots

So basically when playing a game the PC randomly crashes into a reboot. This occurs completely random and without warning.

As suggested in the linked thread I disabled fast startup, which sadly didnt fix the problem.

I also monitored my temperatures which are fine. A workaround that seems to be stable is lowering my graphics settings to very low.

I attached my V2 Logs after a Crash. Windows Version is 1909 (OS Build 18363.720)
