How to Change a CD-ROM Drive

Changing a CD-ROM drive is sometimes necessary due to mechanical failure or simply to upgrade to another unit. CD-ROM drives can be a simple read-only drive, a CD recorder or a DVD unit. Some DVD units can also be used to record to a DVD disc, allowing for greater information storage. Use the following steps to learn how to change a CD-ROM drive.

Instructions

Difficulty: Moderate

1. Disconnect all power to the computer system. Unplug all electrical cables from the back of the computer and press the power button to discharge any remaining energy from the unit.
2. Remove the rear or side of the computer to expose the interior. Thumbscrews are common to remove the panel.
3. Inspect the inside cavity of the computer and locate the rear of the CD-ROM drive. The unit typically sits above all other PC components. Look to the front of the computer and follow the unit back into the system.
4. Unplug the CD-ROM unit's cable from the main system board. The connection can be a thin ribbon-like cable with a bar-shaped connector that plugs into the rear of the CD-ROM unit. The cable may look like a small tube-like cable, as well. Take the power cable from the back of the CD-ROM.
5. Use a screwdriver to remove the retaining screws holding the CD ROM in place. With the screws removed, slide the CD-ROM unit forward until it can be pulled from the front of the PC entirely.
6. Slide the new CD-ROM unit into the existing slot and push into the computer until flush with the front panel. Secure the new CD-ROM in place with the screws that were removed.
7. Attach the existing cables to the CD ROM-drive and plug the power cable in as well.
8. Reattach the rear or side computer access panel and return power to the PC.

Tips & Warnings

• Touch the inside of the computer case before touching any components. This will discharge any built-up static energy.
• Clean the inside of the computer case while it is open. Blow out any dust or debris to ensure a longer life.
• Unplug all power from the computer before attempting any repair.
