I have a A1226 model that has suddenly a developed serious issue that appears to be related to the graphics card according to a engineer. Tried erase and reinstall of lion but still freezing even on initial start up. Looks terminal for the motherboard. Question can a A1260 logic board be fitted in replacement of the original A1226? Many thanks in advance. Alan
