🎮 CompTIA A+ Lab 2.2.13 — Upgrade a Video Card (GPU)
Upgrading a video card improves graphics performance for gaming, video editing, or 3D rendering. This lab demonstrates how to safely remove an old GPU and install a new one.
🧠 Key Concepts
Video Card Types:
Integrated GPU – built into CPU or motherboard; limited performance.
Dedicated GPU – PCIe card with its own VRAM; higher performance.
Key Specifications to Consider:
Interface: PCIe x16 (current standard)
VRAM: Amount and type (GDDR5/GDDR6/GDDR6X)
Power Requirements: Check PSU wattage and required PCIe power connectors (6-pin, 8-pin).
Physical Size: Ensure GPU fits in the case.
Ports: HDMI, DisplayPort, DVI, USB-C – ensure monitor compatibility.
CompTIA Exam Tip: Know how to safely install and connect a GPU, including power cables and driver installation.
▶️ Step 1 — Prepare System
Power off the system and unplug AC power.
Open the case.
Wear an anti-static wrist strap or touch grounded metal.
Remove old GPU if present:
Disconnect PCIe power cables
Release retention clip on PCIe slot
Carefully pull out GPU
▶️ Step 2 — Install New Video Card
Align the GPU with the PCIe x16 slot.
Insert the card firmly until retention clip clicks.
Secure GPU to case with screws at bracket.
▶️ Step 3 — Connect Power Cables
Connect required PCIe power connectors from PSU to GPU (6-pin, 8-pin, or combination).
Ensure snug connection; loose power can cause boot failure or crashes.
▶️ Step 4 — Verify Physical Installation
Check that the GPU is seated evenly, screws are tight, and cables do not obstruct fans.
Ensure proper airflow around GPU for cooling.
▶️ Step 5 — Power On and Install Drivers
Reconnect AC power and boot system.
Install GPU drivers:
NVIDIA → GeForce Experience
AMD → Radeon Software
Verify system recognizes GPU in Device Manager → Display Adapters.
▶️ Step 6 — Test Performance
Run GPU benchmarks or stress tests to verify proper function.
Test monitor connections and resolutions.
Monitor GPU temperatures to ensure proper cooling.
⚠️ Important Notes for CompTIA A+ Exam
PCIe x16 is standard; ensure motherboard has compatible slot.
PSU wattage must meet GPU requirements.
Driver installation is necessary for full performance and features.
Remove old drivers to prevent conflicts if upgrading from another brand.
Use anti-static precautions to avoid hardware damage.
