I set it all up with only 2 ram modules (btw I bought 4 sticks), and powered it on, the lights all come up on the board, but no post screen, no beeps. Tried without the vga, and only ram. Tried without RAM and only VGA, tried all possible combinations and no beeps. i connected the mobo to speaker (System Warning Speaker) and no beeps. So can someone help me out?
