I had a semi-similar issue where games would randomly “freeze” - or rather, you could still hear stuff happening and reacting to key inputs, but the screen was completely frozen. Turns out slightly lowering the clock speed of my GPU basically fixed the issue. I wonder if something similar would be able to extend the life of your GPU too.
I suspect it’s the graphics card. It’s been 6 years with me and it was refurbished when I got it.
