\r Whether you're connecting a monitor to a desktop computer or a new hard drive to the motherboard, getting the right computer hardware cables is essential. A lot of computer manufacturers offer HDMI ports for components like monitors\r in place of traditional audio video cables. However, some models, older machines in particular, still use DVI or VGA cables for monitors and PS/2 cables for keyboards\r and mice. Check the ports in your PC tower to ensure that you have the right wires.\r\r
