[2021] Multiplayer games lead to PC Powering Down

I have an issue where multiplayer games in siege can lead to my computer powering down (No restart or BSOD). It will happen mid-match, usually 2-3 games into a session. I have played for about a year on PC without these issues, they started about a month ago. I have checked temps and specs, nothing is being unusual. I have played other games, including more intensive games, with no similar events. I am suspecting it is a rogue file of some sort, but can't find anything online that has a similar issue. I have reinstalled the game, and that fixed my issue for about 3 days but then it started happening again. I own the game on steam

Any ideas are welcomed.
