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.

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 JCFAN1. This completes the installation.

XTRA INFORMATION
CPU Overheated
If the system shutdown automatically after power on system for
seconds, that means the CPU protection function has been activated.
When the CPU is over heated, the motherboard will shutdown
automatically to avoid a damage of the CPU, and the system may not
power on again.
In this case, please double check:
1. The CPU cooler surface is placed evenly with the CPU surface.
2. CPU fan is rotated normally.
3. CPU fan speed is fulfilling with the CPU speed.
After confirmed, please follow steps below to relief the CPU protection
function.
1. Remove the power cord from power supply for seconds.
2. Wait for seconds.
3. Plug in the power cord and boot up the system.
Or you can:
1. Clear the CMOS data.
(See “Close CMOS Header: JCMOS1” section)
2. Wait for seconds.
3. Power on the system again.

4.4 TROUBLESHOOTING
Probable Solution
1. No power to the system at all
Power light don’t illuminate, fan
inside power supply does not turn
on.
2. Indicator light on keyboard does
not turn on.
System inoperative. Keyboard lights
are on, power indicator lights are lit,
and hard drive is spinning.
System does not boot from hard disk
drive, can be booted from optical drive.
System only boots from optical drive.
Hard disk can be read and applications
can be used but booting from hard disk
is impossible.
Screen message says “Invalid
Configuration” or “CMOS Failure.”
Cannot boot system after installing
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.
