If you are looking to upgrade your current computer system but don't want the hassle of internally installing equipment, it is possible to hook up just about everything you need on the exterior of the system. This includes CD-ROM drives. An external CD drive connects directly through the USB data port on the computer and, once completely installed, functions just like a built in CD-ROM drive on the computer.
Insert a USB data cable into the USB port on the driver, then plug the opposite end of the cable into a USB port on the computer system.
Power on both the computer and the CD-ROM drive (if neither are turned on), then insert the driver installation CD and wait for the installation wizard to load. Follow the prompts of the wizard to completely install the hardware onto the computer.
Insert the CD you want to use into the external, USB CD-ROM. An AutoPlay window should appear, asking what program you want to use with the inserted CD (such as a media player). However, if no AutoPlay window appears, it is possible to access the information by clicking "Start," "(My) Computer," then double-click the removable CD icon and a window appears with all of the files of the CD drive.
