Apple MacBook “Core 2 Duo” 2.0 13" (Unibody) Specs Identifiers: Late 2008 Aluminum - MB466LL/A - MacBook5,1 - A1278 - 2254 @danj Machines runs well until stressed. Sure, bad GPU but NO. The external monitor still runs for another ten minutes then the machine restarts itself. Machine cools off and then runs fine till stressed. The problem is it’s my granddaughters. Possible ESD damage? Possible RAM or RAM slot failure? I am testing the RAM now with a new program I just got today from MicroMat. http://www.micromat.com/store#atomic
@mayer - Sorry I got home late last night and a little tipsy :-) Did you try refreshing the thermal paste yet? Given the age of this system it would be one of the first things I would do here.
@mayor My best guess it could be the fan that is on the computer could be going out I had the same symptoms with my computer awhile back way before I learned about Ifixit and I had to take it into a pro and they said it was the fan so I had it replaced and everything was working fine but if that was not the problem I would definitely say the issue lies with the ram.
