Computer rebooting under certain CPU loads

Bookhouse Boy · November 18, 2020

I've been having a problem with my PC for a month or two now. At a certain point, my computer emits a noticeable click and immediately reboots. I believe that it could be my CPU cooler because I had replaced it with the Noctua NH-D15 a week or so prior to the problem starting. It consistently has occured after about an hour of playing Forza: Horizon 4 and immediately when bots load in when loading in bots during a locally hosted match in CS:GO, and I haven't had it occur any other time using my computer.

I assume that this has to be because of power draw by the CPU because it's happening in response to saving car modifications and significant vehicle collisions in regards to Forza, or more than a few bots spawning in regards to CS:GO. This never happens in graphics heavy/CPU light applications/games, so that's why I'm hesitant to assume that it is a PSU problem like suggested by an LTT discord member. If it is the PSU, then so be it.

The click is likely your PSU's relay and is normal. Is your CPU OCed?

To verify if its a heat/CPU issue rather than power, try running a CPU stress test such as AIDA 64. Monitor temps as well during the test. If it crashes, it could be an issue with maintaining whatever OC/boost clock applied.

I was able to replicate it with csgo by immediately booting it and loading into a map with bots. Nothing else was running and the cpu was at only 28°C. It's definitely looking more like a power problem the more I look into it.

If you can pull up a CPU specific stress test, it would help to be more definitive. Do you have an OC applied?

No, only my graphics card is overclocked. I've ran the OCCT tests for the full hour on cpu, on both vram and gpu for 30 minutes each, and 30 minutes for ram. All I know is that I've only gotten it to trigger with cpu associated things.
