that doesn't give you all the electrical hookups, but it's the best diagram i could find. find the big 24 pin connector on your power supply and the 4 pin power connector. Plug those into the board. That seems to be the only power to the board. You'll have the fan connectors from the fans to the board. You'll have wires from your power supply to your ide or sata drives and wires from your drives to your motherboard.
Just realize that the power supply has wires for the motherboard and the cd/ hard drives. Once you have those set, you also need to connect different wires from your motherboard to your cd/ hard drives. That way, the motherboard has power, and your drives have power directly from the power supply, but the motherboard and drives are also connected directly to each other. everything's connected to everything else.
The wires that control your case (power button, reset button) are the most trouble. just compare the manuals for your case and your motherboard and match up where the wires go.
good luck, don't give up.
