EFORE YOU START
Thank you for choosing our product. Before you start installing the
motherboard, please make sure you follow the instructions below:
Prepare a dry and stable working environment with
sufficient lighting.
Always disconnect the computer from power outlet
before operation.
Before you take the motherboard out from anti-static
bag, ground yourself properly by touching any safely
grounded appliance, or use grounded wrist strap to
remove the static charge.
Avoid touching the components on motherboard or the
rear side of the board unless necessary. Hold the board
on the edge, do not try to bend or flex the board.
Do not leave any unfastened small parts inside the
case after installation. Loose parts will cause short
circuits which may damage the equipment.
Keep the computer from dangerous area, such as heat
source, humid air and water.

NSTALLING CENTRAL PROCESSING UNIT (CPU)
Special Notice:
Remove Pin Cap before installation, and make good preservation
for future use. When the CPU is removed, cover the Pin Cap on the
empty socket to ensure pin legs won’t be damaged.
Pin-Cap
Step 1: Pull the socket locking lever out from the socket and then raise
the lever up to a 90-degree angle.

Motherboard Manual
Step 2: Look for the triangular cut edge on socket, and the golden dot on
CPU should point forwards this triangular cut edge. The CPU will
fit only in the correct orientation.
Step 2-1:
Step 2-2:
Step 3: Hold the CPU down firmly, and then lower the lever to locked
position to complete the installation.
Step 4: Put the CPU Fan and heatsink assembly on the CPU and buckle it
on the retention frame. Connect the CPU FAN power cable into
the CPU_FAN1. This completes the installation.

4.5 TROUBLESHOOTING
Probable Solution
1. There is no power in the system.
Power LED does not shine; the
fan of the power supply does not
work
2. Indicator light on keyboard does
not shine.
System is inoperative. Keyboard lights
are on, power indicator lights are lit,
and hard drives are running.
System does not boot from a hard disk
drive, but can be booted from optical
drive.
System only boots from an optical
drive. Hard disks can be read,
applications can be used, but system
fails to boot from a hard disk.
Screen message shows “Invalid
Configuration” or “CMOS Failure.”
System cannot boot after user installs a
second hard drive.
1. Make sure power cable is
securely plugged in.
2. Replace cable.
3. Contact technical support.
Using even pressure on both ends of
the DIMM, press down firmly until the
module snaps into place.
1. Check cable running from disk to
disk controller board. Make sure
both ends are securely plugged
in; check the drive type in the
standard CMOS setup.
2. Backing up the hard drive is
extremely important. All hard
disks are capable of breaking
down at any time.
1. Back up data and applications
files.
2. Reformat the hard drive.
Re-install applications and data
using backup disks.
Review system’s equipment. Make sure
correct information is in setup.
1. Set master/slave jumpers
correctly.
2. Run SETUP program and select
correct drive types. Call the drive
manufacturers for compatibility
with other drives.
