Okay, so I just got a used keyboard (which I tested before and it was working perfectly), so naturally I wanted to clean it out - I used this video > http://www.youtube.com/watch?v=6Uqsc7M6xIc to do so, and all of a sudden upon plugging the keyboard back in it started typing random letters and symbols when I only typed one letter (ex. Instead of "A" it types "A32k") and other menus pop up and the wepage keeps refreshing over and over again - its like everything went crazy!!! Please someone help me fix this - I have already tried taking the dell keyboard apart and putting it back together several times.
