Asus motherboard problem

[tdark]

I am building a PC using the Asus P7H-55-M Pro. I installed the Intel i3/530 CPU. I bought the ram from crucial that matches this board. I cannot get a video signal. I tried swapping ram, same thing. Now, according to the Asus manual it states I have to use the 8 Pin connector EATX12V , shown in attachment. I have power supply 400w that has only the 4 pin. Has anyone here run into this and will my power supply work with this board. I have read on other forums and some say it will work with the 4 pin but nothing from Asus on this. My CPU fan spins and I can hear the HD turning but no video. I know on these motherboards that in order to use the on board video you would have to use a CPU that has that capability and the i3/530 is one of those CPU's. I wanted to just use the on board and not buy a card. This computer will be used only for office work. Any tips on what to try next to make this thing boot. I have not got any answers from ASUS on this. Thanks, Tom
