[QUOTE="chscag, post: 1067300, member: 46727"] What you described above and from your other posts, leads me to believe like the others, that the problem is again with the logic board. The Apple store more than likely replaced your original board with a refurbished one, which means one that had been repaired and certified OK. Overheating could be caused by an improper application of heat sink compound or even a loose heat sink to the CPU assembly. If the machine did indeed overheat and then shutdown, that's not a good sign. The shutting down is to protect the CPU and other components from being destroyed but each time that it happens, it shortens the life of those same components. Hopefully the repair shop you took it to will be able to correctly diagnose any faults and repair them. Regards. [/QUOTE]
