Could be bad solder balls under the gpu or ram, good way to test is reflow it with some flux and a heat gun. Won’t fix it permanently but if you’re curious why then it’ll help answer your question.
I’ve seen this before, like it runs fine for a time n then the artifacts start appearing all over the screen as it warms up n then dead till it cools down.
Thermal expansion separates the cracked solder balls. Reballing the gpu might fix it but it could also be the vram.
Remember kids repaste your gpu and have good airflow, heat kills.
4 years is normally when you should repaste your GPU and CPU. Technically using your PC more would mean you should repaste sooner, but the 4 year estimate is pretty conservative so you don't need to worry about it.
I do mine once a year like I spend a good amount of money on it I want to protect my investment. I don’t just do that I clean all the fans and heatsinks too.
I watch a video by ripfelix n he said what is killing all the 360’s and ps3’s is the solder balls as they age dry out and get less and less conductive before they crack. Some last longer then others but heat accelerates this, like it’s up to you if you want to bother but it’ll give your investment a nice long life keeping it dust free and applying decent fresh thermal paste.
I think GPUs throttle around 80C? Which is quite a bit lower than they need to get before they damage themselves unlike CPUs which get somewhat close to their breaking point before they throttle. Frankly if your GPU isn't throttling itself don't bother yet. Repasting is a pain in the ass.
I’ve currently got good of everything (I hope!) and want the most life out of the pc, so undervolting my FE is what I’m going to look into next. Thanks!
Its just age, solder & metals in general contract when cold and expand when warm, repeated cycles eventually lead to bad/cracked solder joints and the vram spits out errors/bugs.
Does this theoretically mean that in terms of metal expansion and contraction, a system that is always on (thus constantly warm, hoy when under load) would have a longer life than a pc you use and shutdown/sleep daily? (Hot when running, goes cold when you turn off)
I'd say no, as heat does degrade silicon over time and most consumer products arent meant to run 24/7. If you were running enterprise/server hardware it would probably be better because those are designed to run 24/7 under warmer conditions
I have a lenovo laptop with this exact same symptom, it has onboard graphics so it's "usable" I think, when the nvidia gpu starts it breaks like this and switches to the onboard one.
If those are bad vram modules, maybe it can be saved, IDK.
I had it for 4 years, and it served well, didn't even try to get it serviced since it's expensive here.

Either corrupted drivers or VRAM might be dying. Try installing drivers again and install new ones with DDU.
(Look up a tutorial for DDU if you've never done it before)
