Hi all Couple questions here: My MBP (SR 2,2GHz; NVIDIA 8600GT) has recently been giving garbled displays at random times, and 3D rendering suddenly dropping from 60-70fps and staying instead around 2-3fps sustained. Today, after waking from sleep. the screen, and secondary monitor are black. The computer works, as I can shut down, boot up, hear the hard drive, and I can blindly launch iTunes, etc and play files using the keyboard. Would I be right in saying this is the GPU? I saw apple is offering to repair the faulty GPUs up to 3 years. I purchased mine 1-Oct-2007, so it would qualify. Which brings me to 2 other questions: 1. I don't live within 400 miles of an apple store. We have like a bestbuy and a few small computer shops. I know the bestbuy is authorized reseller. Do they carry parts to fix/warranty this? 2. If I do send it in to apple, i no longer have applecare as I just went with the 1 year warranty. After it was out of warranty I swapped hard drives for a bigger one. Will this cause a problem? Do I need to switch back to the old factory drive?
