Along with what Catdad has said. I have also done the wiggle thing with the cords and I have also knocked my USB port loose. You may also want to check that. If that is loose all you have to do is open up your computer and find the right card and tighten it back up. It's really no big deal to do it, if you are not comfortable doing it your self ask a friend or something that knows how to build computers. If that doesn't work the going rate around me is 50$ an hour for a 10 minute fix. Good luck please let us know.
