PC turning off and turning back on to windows lock screen

[fatherkai]

A couple nights ago my pc did not turn on at all, everything was plugged in and fine, I had to take off the glass panel and take out One of my Two sticks of ram and put it back in and it ended up turning on. But then last night was when my desktop screen turned off twice but the pc was still on and running and I was still able to hear the game (fortnite). I just had to restart my computer both times. Today It happened twice, while playing valorant. But this time the monitor turned off and then actually ended up turning back on and I saw the MSI logo as if it restarted but just like last time, my pc never turned off. And then I was at the windows lock screen, Which didn’t happened last night because before my monitor turned off and nothing happened until I restarted my pc. This time I didn’t need to restart. I also noticed I hear a usb disconnect sound a bit before my monitor turns off and doesn’t turn back on.

TL;DR: Monitor is turning off but PC stays on, First two times the monitor never turned back on. But second the second two the monitor turned back on as If It just reset my PC.

(Also just to clarify, this only happens when I am playing a game, not when I’m casually browsing)
