NVIDIA fault in MacBooks
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.

My MacBook Pro did this
I had these exact problems (and more) with my 1 year old MacBook Pro.
I've used Apple products for about 15 years and have helped bring a number of individuals to the Mac platform. Of all the Macs I've used and owned, this Macbook Pro has given me the most trouble.
I have already sent it to Apple service twice to replace logic board and hard drive components. Even this week the hard drive failed -AGAIN- and I installed a new one myself (since the warranty ran out in June).
The Macbook Pro's, at least from this time period, seem to have a very high "lemon" percentage. It's a shame to pay $3000 and get lockups, black screens, "jumbled" screens, hard drive failures, etc., etc. for an entire year.
With the new hard drive installation, it seems to be running smoothly. However, it's only been 2 days. ;-)
