i have an new x79 dark board (rma board).
 
my old system crashed when i was gaming and shutting down. after an new start, all lights on board was flahing and the post code was running like hell... after support... -> new board now :)
 
so my problem: after installing all my old stuff like before, all is ok but my keyboard (mad catz s.t.r.i.k.e.7) diden´t work. the touch panel from keyboard goes on.... off.... on.... off!!!!
the divice manager from win the same -> error.... ok.... error....
the normal keys from keyboard aren´t without function too...
after short time i become bluescreen :(  after 3 new trys (every time the same) i unpluged my mad catz, plugged my old logitech g19 board and all is ok...
after that, i tryed again after flashing my bioa to 2.13. but diden´t helped.
i checked my mad catz on my other pc. first without driver. keys worked. instatalling driver and software and all functions are ok...
 
so can any1 have an tip what i can do that my mad catz worked like before my rma board?
