EXPERIMENT - 20 :- HOW TO REPAIR LCD MONITOR .


Hardware Installation: PCI Express Graphics Card (GPU)

System Hardware Maintenance & Upgrades Module

Aim / Objective

To safely align, insert, secure, and configure a PCI Express (PCIe) Dedicated Graphics Processing Unit (GPU) on a desktop motherboard, connect supplementary PCIe power connectors, and verify driver initialization.

Tools & Components Required

Item Name Specification / Details Quantity
PCIe Graphics Card x16 Form Factor (Dedicated GPU) 1 Unit
Phillips Screwdriver PH1 / PH2 Magnetic Tip 1 Unit
Anti-Static Equipment ESD Wrist Strap & Mat 1 Set
Power Supply Unit (PSU) With 6-pin / 8-pin PCIe power cables 1 Unit

Installation Procedure

1

Safety Preparation & Electrostatic Discharge (ESD) Protocol

Shut down the system completely. Flip the Power Supply switch to '0' and disconnect the AC power cord. Connect the anti-static wrist strap to an unpainted grounded metal surface of the chassis to discharge static electricity.

2

Case Access & Bracket Clearance

Unscrew and remove the side access panel. Locate the primary PCI Express x16 slot on the motherboard (closest to the CPU socket) and remove the corresponding rear expansion slot covers on the case chassis using a Phillips screwdriver.

3

Card Alignment and Seating

Ensure the PCIe slot plastic retention lock is in the open position. Align the graphics card edge connector precisely over the slot. Press down firmly with balanced pressure on both ends until the retention lock engages with an audible click.

4

Mechanical Security & Power Hookup

Secure the card's metal bracket to the computer case frame using chassis screws. Locate the dedicated 6-pin or 8-pin PCIe power leads from the power supply unit and plug them securely into the GPU top/rear power receptacles.

5

Reassembly, Cable Routing & Display Verification

Reattach the side panel. Connect the monitor signal cable (HDMI/DisplayPort) directly to the **graphics card output ports**, not the motherboard integrated port. Power on the system, enter BIOS/UEFI to verify detection, and initialize driver installation within the Operating System.

Safety & Handling Precautions

  • Always hold the graphics card by its printed circuit board (PCB) edges or cooling shroud; avoid direct contact with gold-plated contact pins or surface-mount components.
  • Verify Power Supply Wattage (TDP) rating before installation to avoid system instability under peak graphical load.
  • Never force the card into the slot. If resistance is met, verify alignment and check if the slot lock lever is unlatched.
