Hi all just built a computer with this board using i5 3570k but i am getting no display. Ive removed ram and swapped them over, changed from my working graphics card to vga, took mobo battery out, checked all power connectors. Theres power to the board and the graphics card so im left with the assumption that the board needs a bios update. So my question is can i flash the bios on that mobo as im hearing you cant with RM version and can i do it through USB flash drive and no display. My other option is to put an i5 2500k in to boot it up and then update the bios after. If the i5 2500k is supported? .
