Hi, I'm having a little computer problems right now. I can't log into my computer at the moment because a few of my keys aren't responding as they should. The signals keep getting messes up, such as my "r" key, which is telling my computer to write out a bunch of different letters, numbers, and symbols, but none that I need. Can I fix this myself, or should I take this to my geek squad friends? Any help on the subject would be most appreciated.
