Lesson 3 • Electrostatic Discharge Prevention

Explains how ESD damages components and how to eliminate the risk. Directly protects the hardware learners will handle throughout the course.

Lesson 1 • PC Architecture and System Overview

Introduces the logical and physical layout of a desktop PC. Establishes the vocabulary and mental model needed for all subsequent hardware work.

Lesson 2 • Memory and Storage Fundamentals

Distinguishes volatile RAM from persistent storage and explains capacity, speed, and compatibility. Prepares learners for component selection decisions.

Lesson 3 • Core Processing Components

Covers CPUs, chipsets, and their roles in computation. Connects processor architecture to real-world performance outcomes.

Lesson 4 • Motherboard Layout and Connectors

Maps every major motherboard zone, slot, and header. Enables confident physical navigation during assembly and troubleshooting.

Lesson 1 • Installing RAM and Storage Devices

Demonstrates correct DIMM slot population order and M.2/SATA drive installation. Slot selection directly affects dual-channel performance.

Lesson 2 • First Boot and Initial Verification

Walks through pre-boot checklist, BIOS entry, and confirming all components are detected. Validates the entire assembly before OS installation.

Lesson 3 • GPU and Expansion Card Installation

Explains PCIe slot selection, bracket removal, and GPU seating. Covers multi-slot cards and proper support to prevent PCIe slot stress.

Lesson 4 • Installing the CPU and Cooler

Guides precise CPU installation and thermal paste application for both Intel and AMD platforms. Proper technique prevents bent pins and overheating.

Lesson 5 • Preparing the Case and Motherboard

Covers standoff installation, I/O shield fitting, and motherboard placement. Correct preparation prevents shorts and alignment problems later.

Lesson 1 • Memory Configuration and XMP/EXPO

Explains how to enable XMP or EXPO profiles for rated RAM speeds. Incorrect settings cause instability, so validation steps are emphasised.

Lesson 2 • Firmware Updates and Recovery

Teaches safe BIOS flashing procedures and recovery from failed updates. Firmware errors can brick a board, so risk mitigation is central.

Lesson 3 • BIOS vs. UEFI Architecture

Contrasts legacy BIOS with modern UEFI, covering boot modes and interface differences. Provides context for every configuration decision that follows.

Lesson 4 • Essential UEFI Settings

Covers date/time, boot priority, fan curves, and power management options. These settings directly affect system stability and energy use.

Lesson 1 • OS Installation Walkthrough

Steps through the full installation process for a modern desktop OS. Covers regional settings, account creation, and activation procedures.

Lesson 2 • System Updates and Security Baseline

Applies OS updates, configures firewall settings, and establishes a security baseline. A patched, secured system is the starting point for all user deployments.

Lesson 3 • Driver Installation and Management

Prioritises chipset, GPU, and network drivers and explains safe sourcing. Correct driver order prevents conflicts and ensures full hardware functionality.

Lesson 4 • Disk Partitioning and File Systems

Explains MBR vs. GPT partition tables and NTFS, FAT32, and exFAT file systems. Partition choices affect boot compatibility and storage efficiency.

Lesson 1 • Dust Management and Thermal Maintenance

Addresses dust accumulation as the primary cause of thermal throttling and failure. Teaches safe cleaning methods for all component types.

Lesson 2 • Storage Health Monitoring

Uses S.M.A.R.T. data and diagnostic tools to assess drive health. Early detection of drive failure prevents data loss for clients.

Lesson 3 • Thermal Paste Replacement

Covers degradation timelines, removal, and reapplication of thermal interface material. Restoring thermal contact directly lowers CPU and GPU temperatures.

Lesson 4 • Software and OS Maintenance Tasks

Covers disk cleanup, defragmentation policy, startup management, and registry hygiene. Software maintenance complements physical cleaning for peak performance.

Lesson 1 • RAM and Storage Fault Diagnosis

Uses memory diagnostics and drive tools to confirm RAM errors and storage failures. Accurate diagnosis prevents unnecessary component replacement.

Lesson 2 • Troubleshooting Methodology

Introduces the six-step diagnostic process: identify, theorise, test, plan, implement, and verify. A consistent method reduces diagnostic time and errors.

Lesson 3 • Thermal and Stability Fault Diagnosis

Links system crashes and shutdowns to thermal, power, or overclocking instability. Teaches temperature monitoring and stress-test interpretation.

Lesson 4 • Display and GPU Fault Diagnosis

Isolates no-display issues to GPU, cable, monitor, or driver causes. Covers integrated graphics fallback and artifact interpretation.

Lesson 1 • Upgrade Assessment and Planning

Identifies bottlenecks through benchmarking and usage analysis before recommending upgrades. Prevents wasteful spending on non-limiting components.

Lesson 2 • GPU Upgrade and Display Optimisation

Covers GPU selection, driver migration, and display configuration for upgraded cards. Includes resolution, refresh rate, and HDR setup.

Lesson 3 • Performance Tuning and Validation

Applies OS-level and firmware-level tuning after hardware upgrades. Benchmark comparison before and after confirms the upgrade's real-world impact.

Lesson 4 • RAM and Storage Upgrades

Covers RAM capacity and speed upgrades and migrating to faster storage. These upgrades deliver the highest performance-per-dollar for most users.
