So I dropped my MacBook a few weeks ago and the hard drive was damaged. I upgraded my HD from 300 to 750gb and my ram from 4 GB to 16. Turned it on and everything worked fine for the install. It randomly gave me this screen once (see below) so I had to hard reset but after that worked fine. Now when I was moving all my stuff back over from time machine it happened again. A friend told me it could be video board and that its irreplaceable?
