Computer Crashing

🔧Technical Issue🖥️Desktop Issue🎮In-game Issue

I recently reinstalled and ive had this issue with other games such as fortnite and apex legends as well. Whenever I try to play the game, randomly throughout my time playing, usually i can barely get past the agent select and then my entire computer shuts off. I suspect its from overheating and ive tried lowering temps using MSI afterburner but it doesnt seem to do anything
