I'm not sure if i've posted this in the right section or not, i'm sorry if i havn't.

I've noticed that my UP arrow button and my Print Screen key's have stopped working on my laptop. The laptop in question is a Toshiba Tecra A9, its running XP Pro SP3.

I've checked if there is any dirt behind the keys or any obivious reasons for the fault but i can't see any.

Any help would be great,

Many thanks
