I am looking up this error on the EVGA forums and somebody said that "FF" stands for "fully functional," of course, I could be getting trolled since obviously you are having an issue right now but have you considered the possibility of your motherboard being DoA? You may need to RMA it with the manufacturer. I had to do the same thing. I had a different issue of course, but that does not matter right now.
The pains of PC gaming... Of course once this is resolved, you will enjoy the fruit of labor...
