I got my macbook 2 weeks ago. Yesterday it hangs (is that what it's called?) and you know, I tried to exit the program that hangs (freezing, not working, loading.. sorry don't know the right word) but the only thing that happened was that the screen turned black. Now it won't work again! The little lamp at the computer is still lighting, but... I can't turn of the computer or try to restart it. I've hold in the start button a thousand times. Still no reaction. Anyone knows what to do? Sorry about my english.
