Computer System
Assembling the Hardware
Installing the Operating System
Compatibility Issues in Hardware
7.1 Assembling the Hardware
Choose the right combination of hardware
e.g. Home use and web surfing
LAN card or modem is needed
no need to install sophisticated hardware
Cost considerations
never go for CPU with the highest speed
choose a hard disk with appropriate capacity
consider reputation and warranty
7.1 Assembling the Hardware
Precautions in computer assembling
Discharge oneself before handling hardware
Hold the main board and expansion cards by
edges
Return the main board and peripherals to
anti-static bags
Disconnect the power before working on the
system
7.1 Assembling the Hardware
Procedure 1: Installing the Power Supply
Fix the power supply
Open the
computer case
Set the voltage supply at
200 - 230 V
7.1 Assembling the Hardware
Procedure 2: Configuring the Main Board
jumper
CPU System Bus Frequency
CPU Clock Ratio
CPU Core Voltage
Setting up jumpers
7.1 Assembling the Hardware
Procedure 3: Inserting CPU into the main
board
The socket, heat sink and fan support base are
mounted onto the main board
Heat sink and fan: prevent overheating
7.1 Assembling the Hardware
Procedure 3: Inserting CPU into the main
board
7.1 Assembling the Hardware
Procedure 4: Inserting the RAM
Check the position of RAM module
Insert the module vertically into
the DIMM slot and push it in
7.1 Assembling the Hardware
Procedure 5: Mounting the main board into
the computer case
7.1 Assembling the Hardware
Procedure 6: Main board signal connections
Completed
connectors
Connecting pins on
the main board
Case signal
connectors
7.1 Assembling the Hardware
Procedure 7: Connecting the Power Supply to
the Main Board
Power supply connectors
7.1 Assembling the Hardware
Procedure 8: Installing the expansion cards
Install the video adapter first
AGP card goes into the AGP slot
Secure the card to the
case with a screw
Position the expansion
card horizontally over
the slot
Install other cards
7.1 Assembling the Hardware
Procedure 8: Installing IDE devices
IDE drives: hard disk, CD-ROMs and DVD-ROMs
Set the jumpers on the drives before mounting
Two IDE channels on the main board
Each channel can attach to two devices
Jumpers on IDE device
7.1 Assembling the Hardware
Procedure 8: Installing IDE devices
1. Mounting the device into
the device bay with screw
2. Align the red strip
on the ribbon cable
7.1 Assembling the Hardware
Procedure 8: Installing IDE devices
3. Insert the connector into
the IDE port
4. Insert the power
supply connector
7.1 Assembling the Hardware
Procedure 8: Installing IDE devices
Master device: alone device on IDE cable
Slave device: second device on the same cable
Ultra ATA 66/100 IDE cable
black: for Master drive
grey: for Slave drive
blue: for connecting to IDE port onboard
7.1 Assembling the Hardware
Procedure 8: Installing IDE devices
Installing CD-ROM drive
Install the drive into an available bay
Insert the power cord into the drive
Connect the drive to the main board via the ribbon wire
Connect the sound cable from the drive to the main
board connector
7.1 Assembling the Hardware
Procedure 8: Installing IDE devices
Installing CD-ROM drive
Connect the sound cable
to CD-ROM drive
Connect the sound cable
to main board
7.1 Assembling the Hardware
Procedure 9: System check
Connect the power cable
Switch on the computer
Check the message on screen
Set up BIOS and install OS if the system works
fine
7.1 Assembling the Hardware
Fine tuning the computer installation
The drives are connected to the power supply
properly.
A fan is attached to the CPU with the power plug
connected to the main board.
Ribbon cables of floppy disk and IDE drives are
attached correctly.
All connections are tight.
CPU core voltage is set correctly.
Cards are inserted fully in slots.
No wires protrude into any fans.
7.2 Installing the Operating System
Clean install
All the content of the hard drive are erased and
everything is installed from scratch
Format the hard drive and install the OS
Back up the data before clean installing an
existing PC
Upgrade
A new OS is installed directly over the previous
version
Old files are left which affect the system
7.2 Installing the Operating System
Materials needed
Hardware documentation
Driver disks of hardware
User’s menu of new OS
Start-up procedures for installing an OS
Start from floppy disk
e.g. Windows 98
Start from CD-ROM
e.g. Windows XP
7.2 Installing the Operating System
Start from floppy disk (Windows 98)
Prepare a boot disk
Check the boot-up sequence
Ensure the partition of the hard disk where OS
is installed is active
Insert the boot disk into the floppy disk
Turn on the power supply
Insert the Windows 98 CD-ROM into the drive
and type “D:\setup.exe”
Follow the on-screen prompts
7.2 Installing the Operating System
Start from CD-ROM (Windows XP)
Check the BIOS boot sequence
Insert Windows XP CD-ROM into the drive
Boot the system
Start installation process
Remove the Windows XP CD-ROM
Reboot the computer

7.3 Compatibility Issues in Hardware
Compatibility problem among main board,
video adapter and expansion cards
Solutions
Place each expansion card in different slots
Take turns at replacing every expansion card in a
certain order
Use step-by-step approach to analyze the
installation of device driver.
