Taking Apart the PC

Identifying key hardware components

• The motherboard and power supply
• Microprocessor and chipset
• Display adapters and memory cards
• Hard disc and DVD drives

Seeing how the PC is designed

• Structuring memory
• Bus types: ISA, PCI, AGP and PCIe
• Distinguishing among x86, Pentium I-IV and Core Duosystems

Basic software components

• Basic input/output system (BIOS)
• Configuring BIOS settings
• Managing device drivers with Device Manager

Troubleshooting Strategy for PCs

Designing a troubleshooting methodology

• Avoiding trouble: preventive maintenance
• Ascertaining where to begin testing
• Pinpointing common failure causes
• Finding the board with the problem

Running the power-on self-test (POST)

• Troubleshooting system faults with POST
• Using POST audio and video error codes
• Determining what POST doesn't test

Employing advanced diagnostic programs

• Testing for motherboard failures
• Isolating keyboard and display problems
• Solving interrupt (IRQ) and I/O conflicts

Working with Basic PC Components

Exploring the motherboard

• CPU types: x86, Pentium, Itanium, Dual-Core, Quad-Core
