So my friends macbook (2.16 leopard, 1gb ram) completely froze on him while he was surfing the net. He tried all the apple tools that are on apples website for macbooks that wont start, and now he is on the startup screen with a picture of a folder with a flashing question mark. He does have applecare but because he is a student in college he's worried about losing time for repair, and work he's done. Any suggestions??
