MacBook Pro errors due to bad NVIDIA hardware?
Long-standing graphics errors in MacBook Pros may be directly attributable to faulty hardware from NVIDIA, reports say. Although NVIDIA has denied accounts of problems in its G84- and G86-based mobile graphics cards, other sources say they have learned that all cards with the chips -- including the GeForce 8600M GT used in MacBook Pros -- may be prone to failure, likely due to ineffective material causing overheating.

Pro owners have been regularly complaining of systems that continue to function, but display only a blank screen when powered on. Investigation has shown that the computers are misidentifying NVIDIA cards as integrated Intel chips, which may be a sign of hardware failure, possibly forcing MacBooks to revert to secondary graphics.
