  2. Objectives • After completing this chapter, you will meet these objectives: • Open the case. • Install the power supply. • Attach the components to the motherboard and install the motherboard. • Install internal drives. • Install drives in external bays. • Install adapter cards. • Connect all internal cables. • Re-attach the side panels and connect external cables to the computer. • Boot the computer for the first time.

  3. Open the Case • Size & shape is the ? • Form factor • Prepare • Lighting, antistatic mats, container for screws • Each case opens differently

  4. Install the Power Supply • Fits one way • Screws attach it to mobo • VIRTUAL DESKTOP: POWER SUPPLY • LAB 3.2 INSTALL POWER SUPPLY

  5. Install CPU & Fan • Put in before mobo goes in case • Put on mat & wear strap • DO NOT touch CPU contacts • Match up Pin 1 • What kind of socket is pictured?

  6. Install CPU & Fan • Apply thermal compound • Helps conduct heat away from CPU • If using an old CPU • Clean off old compound • Isopropyl alcohol ONLY

  7. Heat Sink & Fan • Heat sink draws heat away from CPU • Has a 3-pin power connector for fan • Visit site…

  8. Install RAM • Make sure it’s compatible! • RAM • Temp data storage • Volatile • More= better performance • Align notches • Press until side tabs click

  9. Install Motherboard • Standoffs/spacers prevent mobo from touching case • Align I/O with case • Align screw holes • Tighten screws

  10. Lab • Virtual Desktop: Motherboard • Lab 3.3.3: Install Motherboard

  11. Install Internal Hard Drive • Internal Bays • 3.5” • HDD • Hard disk drive • Screw drive into bay • Virtual Desktop: Internal Drives

  12. Install Optical Drive in External Bay • External Bay • Accessible outside case • 5.25” • Optical CD/DVD • Molex power connector • PATA (IDE/EIDE) data cable • Screw into bay

  13. Install Floppy Drive in External Bay • External Bay • Accessible outside case • 3.5” • Floppy Drive (FDD) • Berg power connector • FDD data cable (wider) • Screw into bay
