To guinaaa: I think you have 2 problems: 1 - the problem of starting this motherboard - I had the same - you should clear the bios of this motherboard (I used the jumper on it) . The second problem - no screen ... miner - you should use built-in videocard of the motherboard (change setting in bios of motherboard)  and you should assign miner to this rig. Sorry for my English.
