I have a asrock extreme 4 in my build and it turns on however nothing displays on the screen, i do not have a graphics card with this build and i tried a different monitor and cable and different type of cable(was using vga tried dvi both didnt work) i sent mymotherboard back to newegg where i bought it and they sent me a new one and this still is happening so i dont think it is the motherboard and i have no idea what it could be now any suggestions means a lot.
