S3 Computer Studies Notes: System Start-up and Configuration

These Senior 3 Computer Studies notes explain how to interpret hardware specifications and set up a personal computer. They describe computer cases, power supplies, ports and expansion slots, followed by procedures for installing components and connecting peripherals. Further sections introduce startup checks, BIOS configuration, disk formatting and partitioning, operating system installation, administrator accounts, and application installation and removal. The text also introduces preventive maintenance and a structured approach to troubleshooting. Step-by-step instructions and a practical observation activity support learning, although several examples use older hardware and Windows XP.
