I took my early-2008 15" MacBook Pro to the Genius Bar after it started freezing on startup in late July, 2012. The Apple rep said that yes, it was the NVIDIA card, but that the four-year free-fix had expired on my computer. Normally, the repair cost for something like that would be $550, but that because of the circumstances the all-in repair cost would be $320. I said I would think about it, especially after looking at all the shiny new laptops in the Apple Store. (I have PC's, an iPad, and an iPhone, and my business needs for a MacBook aren't urgent.)
