looking like its your keyboard driver problem so try rolling back any drivers you installed, or re-installing them in Windows.

check is that happening for alphabets or same thing happening for number also.
if it allover for your key board then this is can happen due to interface problem or due to windows problem.if this problem is only regarding to your alphabets then replace your keyboard.
