So I just opened up my ibook which was in sleep and when I did it went straight to a screen with a white background and vertical lines of lots of different colors and froze this way. I forced shutdown tried turning on and it remained black. I tried again and the screen again went to the colored lines screen. I tried once more and this time it booted up but I am obviously worried this is a much larger issue. Can someone please advise me what to do. I have applecare but I wanted to trouble shoot here first since it will probably me more timely and I think AppleCare might be closes now -- please help!
Thanks
