Hi my 10month old MBP has started freezing not a kernel panic but actually freezing, i'm guessing this is a over heating failsafe as I was running halflife 2 on mac osx using the high performance graphics. Not really sure it should be freezing just because i'm playing a game. So anyway I opened it up to see if it was dusty, it wasnt that bad but i gave it a blast of canned air anyway. Just before I put the case back together I noticed a part of the circuitry, it seemed like it was discoloured in different places, it doesnt look corroded, looks sort of like rainbow colors you get in petrol if that makes any sense, hope this is just normal and i havn't got liquid damage, as I want to take it to apple to get it checked out and obviously water damage = no warranty. Please see photo the area is highlighted red
