My macbook pro A1260 (early 2008) suddenly wont boot up - there's no chime or video, just all of the other usual signs of like such as the drive and fans spinning. Tried all the usual resets and checked the RAM was seated properly but no luck. I had this problem once before a few weeks ago and reseating the RAM suddenly brought it back to life and it booted up again. The macbook is fitted with the NVIDIA Ge Force 8600M GT chip that was decared as faulty but as the mac wont power up with video it's impossible to test specifically to see if the chip is at fault. I have seen many people on these forums with the same problem and a few lucky ones who had the repair done for free regardless of the lack of test possible. I have already taken it to the genius bar and sure enough they presented me with a diagnostic bill for 480euros to replace the logic board. I have heard that these chips can fry the rest of the logic board when they fail, can anyone who has had this confirmed please let me know? I am going back to the genius bar this weekend for a last attempt at persuading them to do it for free (it's within the 4 year extended warranty for this problem). I'd like to know how many people managed to get it repaired even if the computer wouldn't boot up to enable the test. Computer was working perfectly with the exception of minor pixelling at the top of a screen when watching a DVD, could that have been a sign? I know it's a long shot but any advice to help me build an case would be greatly appreciated. So frustrated!!
