i can't help it

My computer is on the blitz. When I went to type today this is what I got: 2230234550300 and that was just hitting random letter keys. Um, OK. Have to send it off. I'm scared they will erase it's memory and leave me with a shell of a computer and I will have to start all over. But, I can't exactly do anything on it unless I develop a code language using 01234 and 5. But, who has time for that?
