Question Monitor losing signal in specific games and the only solution is to restart ?

My monitor has been going off on 3 specific games for a month now, 2 of which are very light. The message that shows up is "lost signal" and it disappears after 2 seconds, the only way to fix it is to turn off the pc and turn it on again. Sometimes it can be fixed by holding a button on the monitor for 5 seconds (the button that turns it off). That closes everything that was opened and sends me to the start screen.

More than half of the times when I lose signal, the audio from the game stops. When it doesn't, I try to do some action in-game (jump, run, shoot, etc) even without seeing anything, but I can't hear the sound of any action, I can just hear other sounds that doesn't depend on my character, which probably means my keyboard isn't responding. Most times the audio doesn't immediately go off, it just gets distorted to the point it's unrecognizable.

I already checked for the GPU temperature when this happens and it was fine, so heat can't be the problem. Just to make sure I used msi afterburner and increased the speed of the fans; nothing changed. Although it was colder the signal was lost. Some of the times this happened I was in a call with a friend, and he could still hear my voice, even though there was no signal, although one of the times, his voice also got distorted and went off eventually.

I've tried changing the monitor cable, added and edited TdrDelay to 60 value, did some things on the nvidia
painel control and windows settings, I've taken the CMOS battery out, cleaned the RAM and changed slots multiple times and maybe more. None of that fixed it on long term. Taking the CMOS battery fixed it for like 2 days (its the best fix yet), but then one day that windows updated, after like 6 hours or more, signal was lost again and taking it out and putting it again does not help anymore. My PC is 1 year old and a few days.
I apologize if something I said wasn't clear, english is not my first language, I've known it for a while, but sometimes I say something wrong.

If you want more information I have a post in another forum, the comments have a lot of information, here's the link: https://pchelpforum.net/threads/monitor-losing-signal-in-a-few-specific-games.92137/

Edit:
The method I used to fix this problem temporarily that lasted the longest was limitating the fps to 60. This fixed the problem for approximately a week, then it started happening again around 2 days ago. I've tried limiting it even more to 30 fps but nothing changed. I can open the few games where the issue is happening but as soon as I join a session or load a save, the monitor goes black and it says I lost signal.

Before this temporary fix, most of the times I lost signal, I also lost sound. Now most of the times I lose signal, there is sound, but I think it's some kind of loop of the most recent sounds in the game. Music always disappears and background sound effects never change much, and if I try to perform an action, the action makes no sound even though it should.

Husky Snow 23.6. I don't think it can be the monitor, because I don't simply lose signal from the monitor, half of the time I also lose any sound and if I don't I try to do things using the keyboard and it doesn't make any sounds (example: trying to walk or run in the game). Since it doesn't make any sound maybe I lost signal to the keyboard too. Alt + f4 also doesn't do anything, and sometimes the signal is back randomly without having to restart but this is extremely rare, and when it happens I'm back at the lock screen.
 
I think it may be something to do with the ram. I changed some memory settings in the BIOS and I lost signal from just turning on the PC. I didn't even have to open a game. Should I get new ram?
