Computer shuts down on its own, then boots back up

    Computer shuts down on its own, then boots back up

    This issue has only started today. I recently got a new motherboard, new CPU, and new memory. Everything had been working absolutely perfectly until today. While playing a game (SC2) my computer will abruptly shut down on its own, then re-boot after a few seconds. All the LED lights inside the comp and on the motherboard turn off as well, so this is not a typical Windows-related reboot (at least I don't think so) and it is somewhat difficult to replicate the conditions that trigger this, as the two instances today were 2 hours apart.

    I haven't changed my usual computer routine heavily since the upgrade and my PSU has never given me issues before and is rather new-ish. I don't know if this is a hardware issue or an overheating issue. I highly doubt it is overheating related, so I don't even know where to begin with this one.

    EDIT: It happened a third time just moments ago, while not under heavy load in-game. The GPU temperature was nominal and the CPU and core temperatures did not go above 20-25 degrees C.

    This is my current PSU

    I have had the PSU for 4 years almost to the day

    won't let me edit my original post, but I've done some further experimenting and found:

    - This hard crash is only happening during the last few missions of SC2's "Legacy of the Void" campaign, which may or may not be relevant. It has been happening almost on cue during a certain mission. It does not happen in custom games

    - It does not occur when running much more load-intensive games where the temperatures for the GPU and the cores are significantly higher
