Learn to build a computer (PC)

This comprehensive and practical course is designed to teach learners how to plan, select components, assemble, configure, test, maintain and troubleshoot a desktop personal computer from individual components. It is suitable for beginners, students, computer technicians, IT professionals, entrepreneurs and anyone who wants to gain practical skills in building and maintaining custom PC systems.

The course begins by introducing the fundamentals of desktop computer architecture and helping learners understand the purpose and compatibility of major components, including the motherboard, processor, RAM, storage devices, power supply unit, graphics card, cooling system, computer case and peripheral devices. Learners will understand how to select components based on performance requirements, budget, compatibility, power consumption and intended use.

Through hands-on practical training, learners will learn how to prepare a safe workspace, handle computer components correctly, install the CPU and cooling system, install RAM and storage devices, mount the motherboard, connect the power supply, install expansion cards and connect internal and external peripherals. Learners will also develop skills in cable management and proper airflow to create reliable and well-organised computer systems.

The course covers BIOS/UEFI configuration, hardware detection, boot configuration and operating system installation. Learners will be guided through installing device drivers, configuring system settings, testing hardware performance and preparing a newly assembled PC for everyday use.

Troubleshooting is an important part of the course. Learners will learn how to diagnose common problems such as a computer failing to power on, no display, overheating, boot errors, RAM problems, storage failures, driver issues and operating system errors. They will also learn preventive maintenance, hardware cleaning, component replacement, system upgrades and basic performance optimisation.

By the end of the course, learners will be able to plan and build a functional desktop computer, identify compatible components, assemble hardware safely, configure BIOS/UEFI, install an operating system and drivers, test the completed system, troubleshoot common faults and perform routine maintenance and upgrades. The course provides practical skills that can support employment, computer repair services, technical support and personal PC building projects.
