Hello all. I have a Macbook Pro 2006 model A1211 specs here http://support.apple.com/kb/sp24 I believe either the GPU or logic board has failed on me. I know its almost a 10 year old computer but it still works well. Anyway it can be fixed and how much? I've built a couple desktop computers before, would this be manageable to replace the logic board on my own? Pictures attached below of error screens. The standard apple start screen appears to be OK but after it starts up I usually get these two screens and I'm unable to sign in.
