One letter does not work on my keyboard. Just one, its the one between the F and H. I have tried another keyboard which works with my other computer and it's still does not work. One uses XP and the other one Vista. Obviously, it is my computer. have no idea what could cause this. Never seen this before. I need help.

I've never seen anything like that before either. My first thought would have been to try another keyboard as well. Perhaps there is some software running that is reserving that G key for something? I know Windows+G shows the gadgets. How long as it been an issue? Any changes that you know of around the time it began? If this was helpful, please vote by clicking the green triangle.
