I have a white macbook that I purchased in beginning of July. I haven't had serious problems with it till just now. I was using my computer and I restarted it and I got a white screen at first. Then you see small thin lines going vertically at the bottom. Soon, the entire screen is filled with different color lines from top to bottom all the way across. Here's a video, I filmed it. http://youtube.com/watch?v=cWsPzS5eKbs And some screen captures of the video, *another thing, hear that weird tapping noise in the middle of the clip? it's from the laptop too. I've restarted it a few times and it's been giving the same outcome. I'm not too sure what the problem might be because I'm a recent Mac switcher from Windows even though I am familiar with computers. I am going to try resetting the ram, but I will wait till replies. Anyone have any ideas what's up??? It would be great help.
