Dell Inspiron 1300 Keyboard Lag

Question

Hello
I'm having trouble with the keyboard on my Dell Inspiron 1300. Unless I type real slow, it keeps missing letters out. This happens in word, online when instant messaging and whenever I type anything - it's like it can't keep up and I'm not a particularly fast typer!

I've trawled the internet for a solution and have even booted the machine up from scratch but it's still the same - any advice realy appreciated!
