You should return that logitech game pad to the store immediately, because that is the source of your problem. I know this because I just came back from the store and I have the same problem. At least I had it until I went there and changed logitech game pad. I believe that I have no problems any more, but I will just have to wait and see what will the new logitech game pad bring. Every time you install a new hardware or new software and something that was working until then is not working any longer, then you have to assume that is up to that new piece of equipment that you have install.
