Study Notes

Computer Assembly and Disassembly

Computer assembly is a crucial skill for computer installation technicians.
Technicians must handle components and peripherals methodically.
Practice improves assembly skills.
Computer assembly involves fitting all internal components to make the system functional.
A specific sequence is followed for each component attachment.
Proper tools and their handling are essential.
Students need to learn the steps for installing each component.
Key components include CPU, motherboard, drives, video and graphics cards, sound card, modem, adapter, and system panel connectors.
Computer assembly is a step-by-step process.
Component arrangement is the first step.
Assembly sequence includes opening the case, installing the power supply, connecting components to the motherboard, installing the motherboard, installing internal drives, connecting internal cables, installing motherboard power connections, connecting external cables, and booting the computer.

Procedure

Step 1: Open the Case. Different methods exist depending on the manufacturer.
Step 2: Install the Power Supply. Usually, four screws secure the power supply. Ensure screws are properly tightened to prevent vibration.
Step 3: Attach Components to Motherboard. Preparing the motherboard involves installing the CPU and its heat sink.
Step 4: Install Motherboard. Metal standoffs are used to mount the motherboard, and prevent the motherboard from touching metal components of the case.
Step 5: Install Internal Drives (Hard Drive). Align the hard drive with the 3.5-inch drive bay, insert it, and secure it.
Step 5: Install Internal Drives (Optical Drive). Position and attach the optical drive to its respective bay. Secure it with appropriate screws. Connect cables to the power supply.
Step 6: Connect Internal Cables. Connect power cables from the power supply to all components. Connect data cables that transmit data between components.
Step 7: Install Motherboard Power Connections. Typical motherboards use either 20 or 24-pin connectors. These are essential for powering the motherboard.
Step 8: Connect External Cables to the Computer. Connect all input and output peripherals.
Step 9: Setting up the Computer System. Connect all components. Reattach side panels.
Step 9: Starting the Computer. Power on the computer following the correct sequence. Power the CPU first, then the monitor.
Step 10: Computer Disassembly. Disassembly is a step-by-step process. Unplug all peripherals and components, then remove screws to detach the case components (fan, hard drive, etc.). Proper methodology is critical to prevent damage. Component identification is necessary.
