- Disconnect Connectors: Unplug all connectors from the motherboard, including SATA power and data cables for HDD and optical drives.
- Remove Fan: Detach the cooling fan from the case.
- Remove Power Supply: Disconnect the power supply, which has 20-pin and 4-pin connectors to the motherboard.
- Remove HDD and Optical Drive: Unplug SATA cables connecting these drives to the motherboard.
Computer Assembly Overview
- Assembly is critical for computer installation and functionality.
- Proper sequence and organization of each component are necessary for a successful assembly.
Steps for Computer Assembly
- Open the Case: Remove screws and slide off the left side panel.
- Install Power Supply: Secure the power supply with screws into the case.
- Attach Components to Motherboard: Install CPU, apply thermal compound, and attach heat sink and fan assembly.
- Install RAM: Ensure RAM compatibility with the motherboard before installing.
- Install Motherboard: Place the prepared motherboard in the case.
- Install Internal Drives: Connect power cable from the power supply to the hard drive and attach SATA data cable from the hard drive to the motherboard.
- Connect Internal Cables: Use power cables to distribute electricity and data cables for data transmission between components.
- Install Motherboard Power Connections: Connect the ATX main power connector, which may have either 20 or 24 pins.
-
Connect External Cables:
- Use a VGA cable to connect the monitor.
- USB connector may be used for keyboards via rear USB ports.
