The problem may be the way you completed your build. I am no expert but I built my own rig earlier this year with no problems - just followed the advice from here if you can access the net somehow - click here
I realise you don't have the same mobo, but the guide has lots of information which will apply with regard to the order of completing your build. Nothing more frustrating than a collection of new bits which won't talk to each other ;-), but all is not lost. There are other sites dedicated to builds so you are not far to be finished. Good luck.
