Preparing for a technical exam in PC Assembly and Maintenance can feel like trying to organize a box of mixed screws without a manual. Whether you are studying for a diploma, a degree, or a professional certification, the secret to passing isn’t just reading—it’s practicing.
Using past papers is the most effective way to bridge the gap between theoretical knowledge and the actual “hands-on” logic required by examiners. To help you succeed, we have curated a comprehensive revision session below based on common exam patterns.

Key Revision Questions and Answers
1. What are the essential safety precautions to take before opening a system unit? Safety isn’t just about the machine; it’s about you. Always ensure the power cable is disconnected. Use an Anti-Static Wrist Strap (ESD strap) to prevent static electricity from frying sensitive components like the RAM or CPU. Never touch the gold-plated “teeth” of any expansion cards, as the oils from your skin can cause corrosion or connectivity issues over time.
2. Explain the role of the BIOS/UEFI in a computer system. The BIOS (Basic Input/Output System) or the more modern UEFI is the first piece of software that runs when you hit the power button. It performs a POST (Power-On Self-Test) to ensure all hardware—keyboard, drives, and memory—is functioning correctly before handing over control to the Operating System. If you hear a series of beeps, that’s the BIOS telling you something is wrong.
3. Distinguish between Preventive and Corrective Maintenance.
-
Preventive Maintenance: This is “health insurance” for your PC. It involves regular cleaning of dust from fans, running disk defragmentation, and updating antivirus software to stop problems before they start.
-
Corrective Maintenance: This is the “emergency room” phase. It happens after a failure has occurred—like replacing a dead Power Supply Unit (PSU) or swapping out a crashed hard drive.
4. Why is Thermal Paste necessary when installing a CPU? Microscopic air gaps exist between the surface of the processor and the base of the heat sink. Since air is a poor conductor of heat, thermal paste fills these gaps to ensure maximum heat transfer. Without it, your CPU will quickly overheat and trigger a thermal shutdown.
5. List three common causes of a PC failing to boot.
-
Loose Connections: Often, RAM sticks or SATA cables have wiggled loose during transport.
-
Power Supply Failure: The PSU might not be providing the correct voltages to the motherboard.
-
CMOS Battery Issues: A dead coin-cell battery can cause the system to lose its configuration settings, preventing a proper boot.
