  1. You should try a usb keyboard, or check the backplate for intrusions. Those backplates have leftover metal tangs that have to be bent out of the way. Check for a grounding or short issue. You can also remove the board and check around and under it for metal objects touching the board.
  2. No good took out the motherboard out of the case and cleaned it up, cleared the cmos and took out the battery tested it outside and is still doing it.
