Mine does this exact same thing! Did you ever figure out what it was or get it fixed? I think mine is a 2008. 15".

It is then the graphics card. if you have a warranty then it will cover it but if not you will have to pay for a repair. or just use the 9600 GT GForce Graphics card.

it can be hardware problem since its not likely to be a software.

I can't help you much about it because im a windows user but soon buy macbook pro one i get enough money ^_^
