so what a crappy night im having... in the course of 10 mins my xbox 360 AND my macbook crash on me! thats karma for ya... so i turn my macbook and i see the white/grey screen and here the welcome sound... but then a whole bunch of vertical colored lines start to fade in. anyone know what in the world is going on?! i havent heard about this before so if anyone knows what i can do about it that would be a great help! thanks much!
