I have thermal paste. Is the GPU easily accessible if I open up the machine?You're not going to like the answer.
Your laptop is 11 years old. . .it fought like a champ, but components fail. MAYBE. . and this is a *HUGE* maybe there's a cable that's starting to get frayed internally, or the thermal paste has dried up and is causing the GPU to overheat..
More likely the GPU is going. Obviously hard to diagnose from the other end of a screen, but either way the cost to repair is going to be more than the machine is worth unless it is a VERY simple solution.
My best advice is: It's time to put the poor thing to rest and get a new machine...

It's 11 years old it really isn't worth fixing or spending any time or money on it's done. Any laptop that lasts more than 5 years is a champ.
LOL thanks guys for your responses. I just hate seeing hardware go to waste like that when it could be used as a dedicated media player or something I could leave by the TV. I try to be resourceful. If this Macbook ends up being a dud, I can repurpose the display panel for another side project.
