Tools and Preparation

To begin the repair, you will need a few tools, including a Phillips screwdriver, a Torx screwdriver, and a plastic spudger. Make sure you have a clean and static-free workspace to prevent damage to the computer’s internal components.

Removing the Case

To access the internal components, you will need to remove the case. Start by removing the screws from the back of the computer using a Phillips screwdriver. Then, gently pry the case open using a plastic spudger.

Disconnecting the Power Supply

Once the case is removed, locate the power supply and disconnect the cables from the motherboard. Make sure to label the cables so you can easily reconnect them later.

Removing the Hard Drive

To remove the hard drive, you will need to disconnect the SATA cable and the power cable. Then, gently lift the hard drive out of its bay.

Replacing the RAM

To replace the RAM, locate the RAM slots on the motherboard and remove the existing RAM modules. Then, insert the new RAM modules and secure them with the clips.

Reassembling the Computer

Once you have completed the repairs, reassemble the computer in the reverse order that you disassembled it. Make sure all cables are securely connected and the case is properly closed.
