  1. you have any idea as to what led to them going dead? I mean if you stuck a paperclip in there and shorted something that caused the controller to burn out you won't be able to do much.

    If you installed some software, try uninstalling it or doing a system restore.

    check in device manager that you don't have any hardware problems.
    reinstall the USB controller drivers.

    does POST give you any errors during power on?
  2. well, nothing not-to-be-stuck in went in dem. they just went off one morning & decided nvr 2 come on again. its a dell n7010
