Installing Hardware
Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount resistors with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the motherboard, you may cause serious damage to the motherboard
or its components.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the clips.
Also, install the cooling fan in a well-lit work area so that you can clearly
see the motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and system
bus frequency for the processor. You may be able to change the settings in the system
Setup Utility. We strongly recommend that you do not over-clock processors or
other components to run faster than their rated speed.
Warning:
1. Over-clocking components can adversely affect the reliability of the
system and introduce errors into your system. Over-clocking can permanently damage the motherboard by generating excess heat in components
that are run beyond the rated limits.
2. Always remove the AC power by unplugging the power cord from the
power outlet before installing or removing the motherboard or other
hardware components.
This motherboard has an LGA775 socket. When choosing a processor, consider the
performance requirements of the system. Performance is based on the processor
design, the clock speed and system bus frequency of the processor, and the quantity
of internal cache memory and external cache memory.
Fail-Safe Procedures for Over-clocking
When end-users encounter failure after attempting over-clocking, please take
the following steps to recover from it.
1. Shut down the computer.
2. Press and hold the “Page Up Key (PgUp)” of the keyboard, and then boot
the PC up.
3. Two seconds after the PC boots up, release the “Page Up Key (PgUp)”.
4. The BIOS returns to the default setting by itself.

Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication
that data is being read from or written to the hard drive. For the LED to function
properly, an IDE drive should be connected to the onboard IDE interface. The LED
will also show activity for devices connected to the SCSI (hard drive activity LED)
connector.
Power/Sleep/Message waiting LED
Connecting pins 2 and 4 to a single or dual-color, front panel mounted LED provides
power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pin 5 and 7 to a momentarycontact switch that is normally open. When the switch is closed, the board resets and
runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a momentary-contact switch that is normally open. The switch should maintain contact for at
least 50 ms to signal the power supply to switch on or off. The time requirement is
due to internal de-bounce circuitry. After receiving a power on/off signal, at least two
seconds elapses before the power supply recognizes another on/off signal.
This concludes Chapter 2. The next chapter covers the BIOS.

About the Setup Utility
The computer uses the latest “American Megatrends Inc. ” BIOS with support for
Windows Plug and Play. The CMOS chip on the motherboard contains the ROM
setup instructions for configuring the motherboard BIOS.
The BIOS (Basic Input and Output System) Setup Utility displays the system’s
configuration status and provides you with options to set system parameters. The
parameters are stored in battery-backed-up CMOS RAM that saves this information
when the power is turned off. When the system is turned back on, the system is
configured with the values you stored in CMOS.
The BIOS Setup Utility enables you to configure:
•Hard drives, diskette drives and peripherals
•Video display type and display options
•Password protection from unauthorized use
•Power Management features
The settings made in the Setup Utility affect how the computer performs. Before
using the Setup Utility, ensure that you understand the Setup Utility options.
25
This chapter provides explanations for Setup Utility options.
The Standard Configuration
A standard configuration has already been set in the Setup Utility. However, we
recommend that you read this chapter in case you need to make any changes in the
future.
This Setup Utility should be used:
•when changing the system configuration
•when a configuration error is detected and you are prompted to make
changes to the Setup Utility
•when trying to resolve IRQ conflicts
•when making changes to the Power Management configuration
•when changing the password or making other changes to the Security
Setup
Entering the Setup Utility
When you power on the system, BIOS enters the Power-On Self Test (POST)
routines. POST is a series of built-in diagnostics performed by the BIOS. After the
POST routines are completed, the following message appears:

Updating the BIOS
You can download and install updated BIOS for this motherboard from the
manufacturer’s Web site. New BIOS provides support for new peripherals, improvements in performance, or fixes for known bugs. Install new BIOS as follows:
1If your motherboard has a BIOS protection jumper, change the setting to
allow BIOS flashing.
2If your motherboard has an item called Firmware Write Protect in Ad-
vanced BIOS features, disable it. (Firmware Write Protect prevents
BIOS from being overwritten.)
3Prepare a bootable device or create a bootable system disk. (Refer to
Windows online help for information on creating a bootable system
disk.)
4Download the Flash Utility and new BIOS file from the manufacturer’s
Web site. Copy these files to the bootable device.
5Turn off your computer and insert the bootable device in your com-
puter. (You might need to run the Setup Utility and change the the boot
priority items on the Advanced BIOS Features Setup page, to force
your computer to boot from the bootable device first.)
6At the C:\ or A:\ prompt, type the Flash Utility program name and the file
name of the new BIOS and then press <Enter>. Example: AFUDOS.EXE
040706.ROM

Trouble Shooting
Start up problems during assembly
After assembling the PC for the first time you may experience some start up
problems. Before calling for technical support or returning for warranty, this chapter
may help to address some of the common questions using some basic troubleshooting
tips.
a) System does not power up and the fans are not running.
1.Disassemble the PC to remove the VGA adaptor card, DDR memory, LAN, USB
and other peripherals including keyboard and mouse. Leave only the motherboard,
CPU with CPU cooler and power supply connected. Turn on again to see if the
CPU and power supply fans are running.
2. Make sure to remove any unused screws or other metal objects such as screwdrivers
from the inside PC case. This is to prevent damage from short circuit.
3. Check the CPU FAN connector is connected to the motherboard.
4. For Intel platforms check the pins on the CPU socket for damage or bent. A bent
pin may cause failure to boot and sometimes permanent damage from short circuit.
71
5. Check the 12V power connector is connected to the motherboard.
6. Check that the 12V power & ATX connectors are fully inserted into the
motherboard connectors. Make sure the latches of the cable and connector are
locked into place.
b) Power is on, fans are running but there is no display
1. Make sure the monitor is turned on and the monitor cable is properly connected
to the PC.
2. Check the VGA adapter card (if applicable) is inserted properly.
3. Listen for beep sounds. If you are using internal PC speaker make sure it is
connected.
a. continuous 3 short beeps : memory not detected
b. 1 long beep and 8 short beeps : VGA not detected
Trouble Shooting
72
c) The PC suddenly shuts down while booting up.
1. The CPU may experience overheating so it will shutdown to protect itself.
Ensure the CPU fan is working properly.
2. From the BIOS setting, try to disable the Smartfan function to let the fan run at
default speed. Doing a Load Optimised Default will also disable the Smartfan.
Start up problems after prolong use
After a prolong period of use your PC may experience start up problems again.
This may be caused by breakdown of devices connected to the motherboard such as
HDD, CPU fan, etc. The following tips may help to revive the PC or identify the
cause of failure.
1. Clear the CMOS values using the CLR_CMOS jumper. Refer to CLR_CMOS
jumper in Chapter 2 for Checking Jumper Settings in this user manual. When
completed, follow up with a Load Optimised Default in the BIOS setup.
2. Check the CPU cooler fan for dust. Long term accumulation of dust will reduce
its effectiveness to cool the processor. Clean the cooler or replace a new one if
necessary.
3. Check that the 12V power & ATX connectors are fully inserted into the
motherboard connectors. Make sure the latches of the cable and connector are
locked into place.
4. Remove the hard drive, optical drive or DDR memory to determine which of
these component may be at fault.
Maintenance and care tips
Your computer, like any electrical appliance, requires proper care and maintenance.
Here are some basic PC care tips to help prolong the life of the motherboard and
keep it running as best as it can.
1. Keep your computer in a well ventilated area. Leave some space between
the PC and the wall for sufficient airflow.
2. Keep your computer in a cool dry place. Avoid dusty areas, direct sunlight
and areas of high moisture content.
3. Routinely clean the CPU cooler fan to remove dust and hair.
4. In places of hot and humid weather you should turn on your computer once
every other week to circulate the air and prevent damage from humidity.
5. Add more memory to your computer if possible. This not only speeds up the
system but also reduces the loading of your hard drive to prolong its life span.
6. If possible, ensure the power cord has an earth ground pin directly from the
wall outlet. This will reduce voltage fluctuation that may damage sensitive devices.
