"The above MacBook Pro is showing broken or distorted video on boot. The cause is a failure of the video chipset (GPU) on the logic board. This is a good real world example of a failed NVIDIA chipset.
Some MacBook Pros (15″ and 17″) with NVIDIA GeForce 8600M GT GPUs that experience the above symptom (sometimes no video) may qualify for a free logic board replacement from Apple (up to 3 years from purchase.)"
