How do you hook up your speakers to your desktop?

For sound cards: Check the back of the computer. If you have some headphone-looking ports in a rectangular shaped metal cutout back there (and there are more than one) put the speakers in the green port. For Computers without sound cards: If you don't have one, look for the mouse and keyboard ports. Close to those, there should be around 3 headphone-looking ports, put it in the green one. Also, it would greatly help if you included the computer model number.
