About two years ago i had to replace my logic board and hd. I was currently under apple care. My Macbook has crashed again and I have received the dreaded question mark upon startup. Since I basically had my computer replaced two years ago I find it odd this is happening again. And is there any way to extend my apple care or am I going to need to buy a new computer? because a new logic board will probably cost almost as much as a new macbook. Someone please send someone please help!
