Once I went on my computer to play a game and my computer froze. So I slapped it and nothing happened. For two hours it wouldn't work so I throw it to the ground and it started to work. Then three hours later it started to freeze again so I got really got mad and bought a new one. It was one of those touch screen computer. So I had it for a good five days and it started to freeze on me so i punched the screen and it started to work again. http://www.youtube.com/watch?v=X3HT4gh-Hso&noredirect=1
