PC randomly reboots during gaming or shortly after closing games

[Laxnd37]

Hey everyone. So my PC has recently started randomly rebooting either during gaming or sometime after closing the game. What happens is a 3-5 second freeze, followed by a reboot back into Windows. This has been happening since late August, although it feels as thought it may have gotten more common recently. I did temp monitoring and everything seems normal (mid to high 50s - low 60s on my i7 8700k) when running a game, and the PSU voltage isn’t fluctuating, so I assume it’s not a bad PSU. Plus, if I don’t run a game, I don’t encounter this issue at all. In my reading, I did see that plenty of other people are having the same exact issue after the May Creator Update for Windows was installed. That is why I mentioned the timeframe above, I installed it on August 29, which is unfortunately too far to rollback. So what do you all think? Do I just do a fresh install of Windows 10? Am I possibly missing something? Having never freshly installed Windows, would my data drives be screwed if I reinstalled Windows? Do I disconnect them if I do, leaving the SSD boot drive attached? Any ideas/input appreciated. Specs below, and everything is from early 2018, except the GPU which is slightly older, the SSD and HDDs which are from 2014/2015, and the PSU which is from March 2019. Thanks!

It only crashes after or during some GPU-heavy workload, then? I'd start with reducing both the GPU and VRAM clocks with Afterburner or something and seeing if that fixes the issue. My gut says it's your VRAM-clocks causing it, but only way of knowing is testing.

i agree with werecaft,

could be a bad psu, but due to it being bought so recently you should probably still have a warranty on that?

I’ll give that a shot tonight. I just wonder why that’d be an issue now, when I haven’t changed them ever.

Yeah I’m pretty sure it’s under warranty still. I initially thought it could be that, because it’s very similar to when my original power supply from 2014 started to give out, but the difference is that in that case, it didn’t matter what I was doing when the pc rebooted. Here, it’s so contextual that it makes me wonder if it is the power supply. Like I had the pc on for about an hour or so watching streams and nothing happened, but then when a game happens, then the issue can happen.

It's just bad luck. Some cards just simply degrade all of a sudden for some reason, like e.g. some years ago, my hubby's GTX970 worked fine for two months and then, without any good reason, its VRAM started causing crashes. It had not been overclocked or anything, all stock-settings, so off it went to RMA. The replacement-card worked fine for years.

Ok. I’ll test that out tonight then. I really hope it’s not that since that’s the priciest possibility.
