heres somethin i jus found on da net Good Fix for Vertical Lines on Macbook
Here is how you fix the vertical line problem on the macbook
restart by resetting the pram (holding command option p r on restart) until you hear 4 chimes
then when you get into os x. open up system pref.
go to display. change the resolution of your screen to anything but normal. then change back to normal. restart computer normally and problem is solved.
I'd be worried more about that sound... it's your HD that's gone apparently.
