Ok so I went to do some "mods" on my macbook pro i have a late 2011 15 inch and read several problems with the GPU going out so i ordered artic thermal compound and a blue silicone heat pad that I put on the heatsink over where the CPU and GPU sit and now when I turn on my macbook I have a green tinted screen I googled and some said it was the connector to the screen but it looks good to me maybe you guys can see somthing I dont I did lose a screw on the metal bridge thing that's pictured
