Im a new guy here, but a friend was telling me there was a way to type something into someone's comp. to ruin it. He said it just keep's running, "Fuck the World", over and over. He say's you can even do it to the computers at the store. If there's any truth to it, Please let me know. Just for fun.

Well, you could get into the screen saver settings and put that as a marcee with a ridiculous password protect prompt after one minute. It seems that's the only logical way to do it without some sort of outside help (CD, email, etc.)

Not a bad idea. Can always take it off also.

True, though I wouldn't do it unless it's at a library or something. Friends would get suspicious and computer stores have cameras.
