Question Why does my monitor disconnect while playing games?

Mar 2, 2023
I currently run a 980Ti, 16GB RAM, i7-6700k, ASRock Z170M-ITX and a 750w PSU. Games have all run perfectly fine the whole time I've had this system, until about a week ago or so, when after 5-20 minutes into playing a game, my monitor loses signal and I have to restart my computer. I've tried a triage of things to fix it. Different monitors, cables, cleaning every crevice of my PC, clean install of drivers, etc. I am currently in an RV connected to power, but I have never had any power issues. My PSU is also a little under two years old, and I'm never overheating on GPU/CPU. What could it possibly be, especially for it to only just now start happening? Games also still run fine until I lose monitor signal.
