That's weird. Also, you're mobo only does x16/x4 crossfire. No good. --- http://i.imgur.com/J0lvB6S.jpg | http://i.imgur.com/DoHj9yA.jpg | http://youtu.be/YXkx-PSwbG4
Haven't you had this problem for a while, or are you a different guy with the same mobo? Have you tried calling Asus? --- You can buy a $500 console and a $500 computer and have two crap machines, or you can spend $1000 building your own computer and have the best of both worlds.
