PC randomly rebooting

h0m3 · January 2, 2021

Hello, how are you guys?

I need some help about my computer, since yesterday my PC started rebooting out of nowhere and I cannot find the cause. My real problem is that its totally random, I run CPU stress (Cinebench R20, R23, Blender, AIDA64), GPU stress (Superposition, Heaven, STTR Benchmark and R6 Benchmark), SSD stress (CrystalDiskMark) for more than 30 minutes just fine, all temps checked using hwinfo, BIOS factory resetted, MemTest for more than 9 hours, no reset. Then I start to use the computer, like browsing the internet, playing some games, opening a virtual machine and them, bam, reboot. Totally random, no BSOD, only a reboot.

I gave up on Windows and installed a Manjaro OS on another SSD, seems to fix the issue, but... When I try to open The Witcher 3 back to reboots again, but this time it was looking at least reprodusible, every time i try to play Witcher 3 the computer restarts, so, I can start testing, exchange the graphics card (i have a RTX 2060, change to a GTX 1060 known working), rebooted. Remove all my SSDs leaving only the new one running Linux, rebooted. Change my 64GB for 16GB, rebooted, removed all hardware from the case in case of a case short circuit, rebooted. Now I'm only left with a CPU, MB and PSU. But... Guess what, i've been cursing Steam client for 1 hour now because Witcher decided to corrupt on me and i cannot get it to work anymore, so, I'm stuck trying to install Witcher to try again crashing my computer with another PSU, CPU and MB. I have all spare parts, my problem is that the reboots are not reliable at all, so I don't really know when i fixed the issue or its just chance that the computer is not rebooting.

I have a R9 3900X, Gigabyte Aorus X570 I Pro (ITX), RTX 2060 (currently GTX 1060), XFX XTR2 850W Gold, 2 x 32GB (currently 2 x 8 GB running without XMP, BIOS stock) and Corsair MP600 500GB (currently a 250GB SATA SSD).

Someone has any idea?

My gut says it's PSU related. You said it's spare parts? How old is it?

If it's not PSU, then more likely motherboard over CPU. CPU's generally don't just shit the bed.

Yeah,

I have some parts, not old. Actually, I have another known working Ryzen computer that i'm exchanging parts. My problem right now is not even testing the hardware, is reliably finding a way to reboot my computer since Steam just crapped out on me, unfortunately, Witcher is totally not opening anymore, on a known working SSD.

I'm currently trying to test the PSU, installing another game (Team Fortress 2) to see if that one maybe reboots the computer. I'm honestly out of ideas. If it was somehow load related i could just run a benchmark, but unfortunately they just work, also some games just work, like SOTTR. I'm thinking about installing Linux on another SSD and install Steam again, then try Witcher 3 once more.

Your steam and witcher problem is irrelevant to your hardware issue.

Take the PSU out of the Ryzen computer, and see what happens for a couple days.

Yeah,

That is basically the solution that I was thinking right now, the problem is that i also work with this computer, so I cannot like test it for a few days each component because if it starts crashing on me during my work i would be having a very bad day.

I can use another computer, sure, but then i cannot test this one because the reboots seems to be connected to usage, if i leave the computer running some benchmark, game or something, it doesn't reboot for whatever reason. I have to keep opening or closing stuff until it randomly reboots.

Sadly to report,

It is the CPU. I've managed to get Witcher 3 running, and i've exchanged everything. With the 3900X the computer reboots but even putting my 2200G on the 3900X machine doesn't reboot it. I'll make some more testing using the 2200G but it looks like the 3900X just died!

And thats really sad because i didn't do any overclock on it, it always ran stock (i'm not a huge fan of overclocking). I'll just RMA it once i finished all the testing to make sure.
