Starting It Up - Adding Graphics & Peripherals

Connectors Overview

  • Power Connectors:

    • Motherboard Power Connector: Large connector that powers the motherboard.

    • Molex Connector: Legacy 4-pin connector used before SATA for power.

    • SATA Power Connectors: Modern machines primarily use these for hard drives; Molex to SATA adapters are commonly available.

Connecting Power Supply

  • Step 1: Connect power supply to the motherboard using the large power connector.

  • Step 2: Connect the CPU power using the 8-pin Molex connector.

    • Note: The connection may require a firm push.

    • Result: Power supply is now connected to both the motherboard and the CPU.

Case Cables Connection

  • Case Cables: Vary by model and include buttons and lights.

  • Secure case cables to motherboard; use motherboard guides for a clean installation.

Installing the Graphics Card

  • Step 3: Insert graphics card into the PCI Express slot on the motherboard.

    • Action: Apply pressure until you hear a click.

  • Secure graphics card to the case (installation may vary by case).

Closing the Computer Case

  • Final step: Remove anti-static bracelet before putting on the case lid.

  • Result: The computer is built and ready for peripherals.

Connecting Peripherals

  • Keyboard Connection: Use USB connector to plug into the desktop.

  • Mouse Connection: Similarly, connect mouse using USB.

  • Monitor Connection:

    • Cable Used: DisplayPort cable; connect one end to the desktop and the other to the monitor.

Testing the Setup

  • Power On: Turn on the computer to check functionality.

    • Indicators:

      • Blue light signifies power.

      • If monitor receives a signal, system is booting up.

  • Successful Boot: Messages appearing on the monitor indicate successful startup.

Troubleshooting Common Issues

  • If the computer does not start:

    • Check if the power supply provides sufficient wattage.

    • Ensure all connectors are placed correctly.

  • Error Message: "Non-system disk or disk error" indicates the need for an operating system.

Future Learning

  • Next lesson: Understanding operating systems, their types, and installation procedures.

Reflection on Achievement

  • Building a computer involves:

    • Learning about individual components and their functions.

    • Successfully assembling components into a working system.

  • Recognize the accomplishment of completing the build.
