Well, senior. You should be able to find a portion of the motherboard that has several pins group together. Each pin set is used for different functions regarding the buttons & other products you have on the front of your PC. For example, when you are booting up you will sometimes notice a green or amber light on the front of your PC glowing. This is only one portion of the many different types of components you will need to hook up in order to be bale to start using your newly acquired motherboard. I suggest finding out what type of MOBO you have, and ordering a diagram from that particular dealer. This way you know exactly where to hook up the pwr, sound, usb, etc. Good luck.
