Hi Guys, I got a serious problem. Can you guys translate this? What is the problem and what to do? More info right here! http://forums.macrumors.com/showthread.php?t=1406963&highlight=codes+translate I've changed the Memory from 2x2gb to 2x4gb... Could this be the problem? and should I try to put the old memory back in again? I really need your help! Thanks!
