I have a 13" 2.26ghz i2d macbook pro that I can only get to boot in safe mode. When I hook the hard drive up to an enclosure and USB port I still have the same issue. From looking around online I've gathered that its the GPU. My question is, is this something that I can do myself? Also if it is, where can I pick up a graphics card for it (is my best bet a used mbp on ebay?)? thanks for the input guys.
