[SOLVED] PC rebooting intermittently when playing games

Hi there! So recently I upgraded most of my rig and after playing a few games I noticed that in some of them my PC just randomly rebooted. It doesn't seem to be a temperature issue, my GPU doesn't go over 70 °C - 75 °C and my CPU maintains at 45 °C - 50 °C.

It is curious that it mostly happens when I play CS:GO or Fortnite, it happened a few times while playing LoL. I can play PUBG and Dota2 in full graphics (ULTRA - just to put some serious stress on my card and CPU, even RAM) without it crashing or anything, but as soon as I get off the "Battle Bus" in Fortnite, or start a match in CS:GO, it reboots with no crash screen or specific error message.

I want to clear out that there are moments where I can play continuously for a while without my PC rebooting, but sometimes (most of the time) it just reboots with no explanation as soon as the match starts.

I will appreciate your help on this, thanks in advance!

EDIT:

I want to add that I initially thought it was an issue with the RAMs, and I tried a few things like placing them in different slots (respecting the rule 1-3 and 2-4) and booting with only 1 installed (tried them both) and even though the PC always ended up rebooting it lasted longer in-game when there was only 1 plugged in than when both were plugged.

I will definitely try this tomorrow, thanks for answering and sorry for the delayed response.

I was thinking about the motherboard itself, do you think the motherboard might have something to do with it?
