Caps Lock not working

Ok. For some reason I can't get my caps lock to work. I don't know why it stopped working and I've never had this problem before. I've checked at startup to see if I can get it to work and no luck. I can't get it to work while windows is running or any word processors. I can't figure it out. I have a laptop is that makes any difference. I checked for updated drivers and no luck. My warranty is also over. Do you guys have any ideas. I haven't reinstalled windows in over a year if that might affect anything. and I believe I've had a fair amount of spyware collected and removed over that time. Any help would be great.

My bad. I think this should go in the hardware section. If a mod or admin could move it that would be appreciated.

A mod has moved it.

Also, have you checked the keyboard properties? (It's under My Computer, Settings, Keyboard) On the Hardwaretab, see if the keyboard is atleast properly installed.
And of course, it could always be that the key is just broken. You could pull it out and tip with a pen on the action point. (may not work with your laptop though).
