Okay, I posted a thread a few weeks ago telling everyone about my HD problems..well I sent it in for repairs and they fixed it..no more humming sounds, it doesn't get hot anymore, etc..BUT when I got it back this morning I turn it on and now the screen glitches..I get vertical lines popping up..the screen goes black occasionally ( especially when I minimize/maximize windows) Now there telling me there might be a problem with my logic board..well..to make a long story short..there sending me ANOTHER box tomorrow..for it to be shipped out AGAIN..anyone who buys a Mac should seriously consider buying the AppleCare..whether they can afford it or not..lol
