Hi, I don't think, that the simple graphics of Mathematica can overheat the chip. AFAIK the problem comes form a insufficient cooling in the laptop. You should ask your laptop manufacturer if you model apply to the problems. But official neither nVidia nor a laptop manufacturer have confirmed the problems.
