Make an Ubuntu live USB, boot into it, and then go dick around on the internet for a couple of days while in Linux. If it works fine for a bit then suddenly crashes, you have a hardware problem. If it lasts a few days without crashing, you have a software problem.
The thing is though, I can go for days or weeks without crashing if I stay away from certain games and programs. Things like GTAV or modded Bethesda games run through mod managers seem to trigger it
It doesn't happen with every game though and isn't always connected to the GPU being under high load, which makes me think it might be something to do with loading things from memory etc.
One crash trigger I've noticed is alt-tabbing back into a game after doing somerthing else for a while. It seems to just die when it tries to resume whatever was going on
That's a GPU problem, definitely do what @swampfox said. Take note of your GPU driver's current version, update it if there is an update. If that doesn't work downgrade it to a version earlier than your current. If that still doesn't work downgrade to even earlier or uninstall and reinstall the driver. If none of that works, you might be looking at a hardware issue in your GPU.

In that case, whoever said to do a GPU testing program was probably right.
Well, I ran the demo for 3DMark. My Time Spy score is "Great" but all the other tests are behind a paywall

Sounds like something to do with virtual memory, but hell if I know how that'd break or how you'd test it.
