My 15" mid-2014 MacBook Pro has been working well since I bought it new 5+ years ago. But in the past couple months, it's now started abruptly freezing, and then shutting down after a few moments, or just shutting down without the freeze. The trigger seems to be some sort of graphically intense process like having a bunch of web pages open and kicking on a video, or video editing. Usually this will all be accompanied by the fans kicked to high gear. If I just do simple stuff it'll be fine. It also seems like it's worse when it's on battery vs when I have a power adapter connected.
I know it's not an OS or Data issue because I have two partitions, both running two different OSes, one Mojave and the other High Sierra and the problem happens on both.
I've done the SMC reset and the NVRAM (or PRAM) reset. No help.
I came across this vid Fix Thermal Throttling on Your Mac?! by Snazzy Labs where he discussed using thermal paste as a way to boost performance, but didn't mention as a way to stop what seems to be some sort of overheating issue. I asked as a comment on this and Snazzy Labs responded:
The computer otherwise is working fine and I Really don't want to replace if I don't have to. But assuming it's a faulty board, what kind of cost would I be looking at? And how does hard drive, RAM, etc all work? Are they all attached to the board?

"Might be a bad GPU. If you’re able/willing, install Windows and then HW Monitor to get real GPU temps and you can be sure it’s just throttling before you open it and replace everything to no resolve if it’s a faulty board."
