Keyboard Problems.
 

Ever since I re-installed my keyboard some of the keys don't seem to work right. I know that's a bit vague so here is the proper explanation. SHIFT + 2 = @ instead of ". SHIFT + 3 = # instead of well, actually I haven't found out where the symbol for a British pound has gone yet.

Any ideas people?

What do you mean by "reinstalled my keyboard"? Do you mean that you reinstalled the software for the keyboard?

...generally, I'd say that you should try replugging the thing into your computer.
Is the keyboard, as I assume, a USB keyboard of sorts?

Maybe it set it self to the wrong keyboard layout. Which layout are you looking for exactly?

Control Panel > Date, Time, Language, and Regional Options > Regional and Language Options > Languages > Details.

Add the keyboard you want, and delete the one you don't want.
