Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any
component.
• Use a grounded wrist strap or touch a safely grounded object or
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
• Before you install or remove any component, ensure
that the ATX power supply is switched off or the power cord is detached
from the power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
Onboard LED
The motherboard comes with a standby power LED that lights up to indicate
that the system is ON, in sleep mode, or in soft-off mode. This is a reminder
that you should shut down the system and unplug the power cable before
removing or plugging in any motherboard component. The illustration below
shows the location of the onboard LED.

1.5 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to
ensure that the motherboard ts into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and damage
motherboard components.
1.5.1 Placement direction
When installing the motherboard, make sure that you place it into the chassis in the
correct orientation. The edge with external ports goes to the rear part of the chassis
as indicated in the image below.
1.5.2 Screw holes
Place six (6) screws into the holes indicated by circles to secure the motherboard
to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side towards
the rear of the chassis

The motherboard comes with a surface mount LGA775 socket designed for the
Intel® Core™2 Duo/Pentium® D/Pentium® 4 and Celeron
•
Make sure the AC power is off before you install the CPU.
• If installing a dual-core CPU, connect the chassis fan cable to the chassis
fan connector to ensure system stability.
•
Upon purchase of the motherboard, make sure that the PnP cap is on
the socket and the socket contacts are not bent. Contact your retailer
immediately if the PnP cap is missing, or if you see any damage to the PnP
cap/socket contacts/motherboard components. ASUS will shoulder the cost
of repair only if the damage is shipment/transit-related.
•
Keep the cap after installing the motherboard. ASUS will process Return
Merchandise Authorization (RMA) requests only if the motherboard comes
with the cap on the LGA775 socket.
• The product warranty does not cover damage to the socket contacts
resulting from incorrect CPU installation/removal, or misplacement/loss/
incorrect removal of the PnP cap.

1.6.2 Installing the CPU heatsink and fan
The Intel® LGA775 processor requires a specially designed heatsink and fan
assembly to ensure optimum thermal condition and performance.
•
When you buy a boxed Intel® processor, the package includes the CPU fan
and heatsink assembly. If you buy a CPU separately, make sure that you
use only Intel®-certied multi-directional heatsink and fan.
•
Your Intel® LGA775 heatsink and fan assembly comes in a push-pin design
and requires no tool to install.
•
If you purchased a separate CPU heatsink and fan assembly, make sure
that you have properly applied Thermal Interface Material to the CPU
heatsink or CPU before you install the heatsink and fan assembly.
Make sure that you have installed the motherboard to the chassis before you
install the CPU fan and heatsink assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, making sure that
the four fasteners match the holes
on the motherboard.
Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the CPU
fan connector.
