Whats wrong with this motherboard? Reaching deadline!!

[HealedWolf]

+I have already purchased and carefully assembled my PC and after powering it up, no instructions or bios information appears on the monitor.

+ I researched and found a similar cause: http://pcpartpicker.com/user/HealedWolf/saved/P9Kkcf

+ I have already filed an RMA but hesitant to get it replaced verses refunded. If refunded it would be the sale price and I would have to spend extra money to get another motherboard. Is the line of motherboards defective or is not compatible with my parts.

Depending on the revision, rev 4.1 needs BIOS F3 on it to support that CPU. This is the 2nd to last CPU

Rev 5 needs BIOS FA. This is the first and only BIOS. Rev 6 needs BIOS F2 which is the latest BIOS. So what revision is the mobo??

One reason its not doing anything, is the BIOS on the mobo now doesnt support that CPU without a BIOS update
