Once i was on my computer and i was playing music (Justin bieber of cource) anyways, the computer randomly stopped. I didnt know what to do because of the fact that i was home alone. But when i hit it it started to work again which was kind of wierd.So now everytime that my computer, t.v or anykind of things like that i hit it if it stops working. If hitting it doesnt work then i probley would resart the whole thing but usually it works just hitting it. I have done that a million times and so has like everyone in my family, im pretty sure that atleast ionce in a while everyone has done it in there lives ANother thing you could hit and it might work better is a pop machine and a candy machinewhen it gets all crazy. That is my story about how you can hiut a computer or a t.v or a dvd player or anything and it usually works fine:)
