About the free online course

Want to understand what really happens inside a computer and how devices connect and communicate on a network? This free online course is designed to take you from the fundamentals of PC hardware to practical, real-world troubleshooting skills used in IT support roles. You will build a clear mental model of how each component works, how it interacts with the rest of the system, and how to diagnose problems confidently instead of relying on guesswork.

You will explore core computer architecture concepts and learn what makes a system perform well or fail under pressure. From the CPU and multi-core processing to memory behavior and common bottlenecks, the course helps you connect theory with everyday symptoms like slow performance, unexpected shutdowns, overheating, or boot issues. You will also gain insight into motherboard design, sockets, power connections, and maintenance considerations that matter when assembling, upgrading, or repairing computers.

Storage is another key focus, giving you a practical understanding of how drives organize and retrieve data, how partitions and file systems shape reliability, and why certain sounds or behaviors can signal a failing disk. Along the way, you will learn how firmware and startup routines work, including BIOS settings, POST behavior, and boot order changes—essential skills for bringing non-booting machines back to life.

The course rounds out your toolkit with common peripheral and power topics such as SMPS fundamentals and printer technologies, so you can handle typical office and home-user issues end to end. With videos and exercises to reinforce learning, this is a solid step toward entry-level tech support and help desk readiness. If a certificate fits your goals, you will be able to validate your progress and showcase your skills more confidently.
