- 1). Shut down your computer, and remove the power cord from the back. Remove the retaining screws that hold the case in place. Most computers use one screw at each corner on the back of the PC.
- 2). Pull the case removal lever to lift the cover off of the unit. For desktop computers, this lever is typically on the top of the unit, while tower computers tend to place the lever on the side. Set the case cover aside.
- 3). Locate the appropriate slot for the CD-ROM drive. This slot is generally located right underneath the computer's hard drive. Slide the CD-ROM drive into this slot, and secure it by inserting the included screws into the holes in the side of the drive.
- 4). Trace the cable that runs from the computer's hard drive to the system board. Look for an extra attachment, roughly in the middle of the cable. Attach that to the back of the CD-ROM if it is available.
- 5). Attach the cable that came with the CD-ROM drive if no extra connector is available. Attach the other end of the cable to the system board, right next to where the hard drive cable is attached.
- 6). Locate the power supply in the back of the computer. This is a large box with cables coming off of it and running to the various devices in the computer. You should see a power cable running from the power supply to the hard drive. Locate an unused power connector, and attach it to the CD-ROM drive.
- 7). Power on your computer, and right-click on the "My Computer" icon. Look for the CD-ROM drive in Windows Explorer--this drive will typically be designated as the "D" or "E" drive. Download and install a software driver from the manufacturer if the CD-ROM is not recognized.
