Building a Custom Built computer step by step process simplified for beginners

Here’s a basic step-by-step guide for physically building a PC:

  1. Prepare the Work Area:
    • Choose a clean and well-lit workspace with sufficient room to assemble the components.
    • Place the motherboard box on a flat surface and use it as an anti-static mat to protect the components.
  2. Install the Power Supply Unit (PSU):
    • Determine the PSU’s mounting location at the bottom or top of the case.
    • Align the PSU with the mounting holes in the case and secure it using screws provided.
    • Connect the necessary power cables to the PSU, such as the motherboard power cable (usually a 24-pin connector) and CPU power cable (typically an 8-pin connector).
  3. Mount the Motherboard:
    • Align the motherboard’s I/O shield (included with the motherboard) with the corresponding opening in the case and gently press it into place.
    • Carefully position the motherboard over the standoffs (raised screws) in the case that match its form factor.
    • Align the screw holes on the motherboard with the standoffs and secure the motherboard to the case using screws.
  4. Install the Processor (CPU):
    • Unlock the CPU socket on the motherboard by lifting the lever.
    • Align the notches or markers on the CPU with the corresponding indicators on the socket.
    • Gently place the CPU into the socket and ensure it sits flat. Do not force it.
    • Lower the lever to secure the CPU in place. It may require some pressure, but avoid excessive force.
  5. Install the Memory (RAM):
    • Locate the memory slots on the motherboard.
    • Unlock the memory slots by pushing down on the tabs at either end.
    • Align the notch on the RAM module with the slot and insert it at a slight angle.
    • Apply even pressure on both ends of the module until it clicks into place.
    • Repeat the process for additional RAM modules if applicable.
  6. Connect the Storage Drives:
    • Mount the SSDs or HDDs into the designated drive bays using screws.
    • Connect a SATA data cable to each drive and the motherboard’s SATA ports.
    • Connect a SATA power cable from the PSU to each drive.
  7. Connect the Case and Power Cables:
    • Connect the case’s front panel connectors (power button, reset button, LEDs, etc.) to the corresponding pins on the motherboard. Refer to the motherboard’s manual for the correct pinout.
    • Connect the case’s USB, audio, and other ports to the motherboard if applicable.
  8. Install the Graphics Card (if applicable):
    • Identify the PCIe x16 slot on the motherboard.
    • Remove the expansion slot covers on the back of the case that align with the PCIe slot.
    • Align the graphics card’s PCIe connector with the slot and firmly press it in until it clicks.
    • Secure the graphics card to the case using screws or brackets if necessary.
  9. Connect Power Supply Cables:
    • Connect the remaining power cables from the PSU to the motherboard, including the CPU power cable and any additional power connectors required by the motherboard or graphics card.
  10. Double-Check Connections:
  • Ensure that all cables and components are properly connected and secured.
  • Check for any loose connections or cables obstructing the fans or other components.
  1. Close the Case:
  • Place the side panels back on the case and secure them with screws.
  • Ensure all screws are tightened but avoid overtightening.
  1. Final Checks:
  • Verify that all components are securely installed and connected.
  • Check that the CPU cooler is properly installed and making good contact with the CPU.
  • Ensure that all fans are connected to the appropriate headers on the motherboard
