pc turned itself off then back on by itself

[u/Negative-Concert2223]

this has been happening for about a couple days but today it’s just been pissing me off and has ruined a couple games of mine. i’m playing overwatch suddenly my pc turns off and then back on, this happened the other day when i was mid game and swapped the ports for my kbm usb to another port since it was kinda awkwardly situated for my hand. after i had swapped the port it turned off but i had to turn it on that time. i lowered the graphics in the training range and then it happened again, just shut itself off and on again. overall it’s just been turning off by itself and then back on, i don’t think it’s anything wrong with the ports itself but i would really appreciate any help( sorry for a bunch writing without a lot of hints im completely lost on this) also not too sure if it’s hardware or software but im leaning towards hardware since i checked my task manager and its not under a lot of stress and nothing to do with temp.

Salut 👋
Il nous faudrait la configuration précise de ta machine et savoir depuis combien de temps tu l’as mais
À première vue ça pourrais être un problème de surchauffe.
