Hey! I have the Early 2008 MBP 15in with the dreaded 8600GTM that will blow up" at any random time. School is starting soon and I am worried that this thing will just stop working at the worst time. IE when a paper is due, my video production class needs my power etc.etc. As of now the computer runs really hot with just iTunes, Safari, and Finder. I've already had the computer repaired by Apple for a cracking hinge, non clicking trackpad, and dead pixels which they did not fix. What should I do? I am going to buy and external HDD soon to back up but I don't see how that would help if I can even access the data until I get the computer fixed. What would you do in this situation?
