Important:
Electrostatic discharge (ESD) can damage your board, processor, disk drives, add-in
boards, and other components. Perform installation procedures at an ESD workstation
only. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If
a wrist strap is unavailable, establish and maintain contact with the system chassis
throughout any procedures requiring ESD protection.
System Memory
The system board is equipped with one 204-pin SODIMM sockets that support DDR3 memory
modules.
Important:
When the Standby Power LED lit red, it indicates that there is power on the board.
Power-off the PC then unplug the power cord prior to installing any devices. Failure to
do so will cause severe damage to the board and components.

Installing the DIM Module
5. Grasping the module by its edges, align the module into the socket at an approximately 30
degrees angle. Apply firm even pressure to each end of the module until it slips down into
the socket. The contact fingers on the edge of the module will almost completely disappear
inside the socket.
Note:
The system board used in the following illustrations may not resemble the actual one.
These illustrations are for reference only.
1. Make sure the PC and all other peripheral devices connected to it has been powered down.
2. Disconnect all power cords and cables.
3. Locate the SODIMM socket on the system board.
4. Note the key on the socket. The key ensures the module can be plugged into the socket in
only one direction.
6. Push down the module until the clips at each end of the socket lock into position. You will
hear a distinctive “click”, indicating the module is correctly locked into position.

The BIOS is a program that takes care of the basic level of communication between the CPU
and peripherals. It contains codes for various advanced features found in this system board.
The BIOS allows you to configure the system and save the configuration in a battery-backed
CMOS so that the data retains even when the power is off. In general, the information stored
in the CMOS RAM of the EEPROM will stay unchanged unless a configuration change has been
made such as a hard drive replaced or a device added.
It is possible that the CMOS battery will fail causing CMOS data loss. If this happens, you need
to install a new CMOS battery and reconfigure the BIOS settings.
Note:
The BIOS is constantly updated to improve the performance of the system board;
therefore the BIOS screens in this chapter may not appear the same as the actual
one. These screens are for reference purpose only.

The picture seems to be constantly moving.
1. The monitor has lost its vertical sync. Adjust the monitor’s vertical sync.
Troubleshooting Checklist
2. Move away any objects, such as another monitor or fan, that may be creating a magnetic
field around the display.
This chapter of the manual is designed to help you with problems that you may encounter
with your personal computer. To efficiently troubleshoot your system, treat each problem individually. This is to ensure an accurate diagnosis of the problem in case a problem has multiple
causes.
3. Make sure your video card’s output frequencies are supported by this monitor.
The screen seems to be constantly wavering.
Some of the most common things to check when you encounter problems while using your
system are listed below.
1. The power switch of each peripheral device is turned on.
1. If the monitor is close to another monitor, the adjacent monitor may need to be turned off.
Fluorescent lights adjacent to the monitor may also cause screen wavering.
2. All cables and power cords are tightly connected.
Power Supply
3. The electrical outlet to which your peripheral devices are connected is working. Test the
outlet by plugging in a lamp or other electrical device.
When the computer is turned on, nothing happens.
4. The monitor is turned on.
1. Check that one end of the AC power cord is plugged into a live outlet and the other end
properly plugged into the back of the system.
5. The display’s brightness and contrast controls are adjusted properly.
2. Make sure that the voltage selection switch on the back panel is set for the correct type of
voltage you are using.
6. All add-in boards in the expansion slots are seated securely.
3. The power cord may have a “short” or “open”. Inspect the cord and install a new one if
necessary.
7. Any add-in board you have installed is designed for your system and is set up correctly.
Monitor/Display
If the display screen remains dark after the system is turned on:
1. Make sure that the monitor’s power switch is on.
2. Check that one end of the monitor’s power cord is properly attached to the monitor and the
other end is plugged into a working AC outlet. If necessary, try another outlet.
3. Check that the video input cable is properly attached to the monitor and the system’s
display adapter.
4. Adjust the brightness of the display by turning the monitor’s brightness control knob.

Hard Drive
System Board
Hard disk failure.
1. Make sure the add-in card is seated securely in the expansion slot. If the add-in card is
loose, power off the system, re-install the card and power up the system.
1. Make sure the correct drive type for the hard disk drive has been entered in the BIOS.
2. Check the jumper settings to ensure that the jumpers are properly set.
2. If the system is configured with two hard drives, make sure the bootable (first) hard drive
is configured as Master and the second hard drive is configured as Slave. The master hard
drive must have an active/bootable partition.
3. Verify that all memory modules are seated securely into the memory sockets.
4. Make sure the memory modules are in the correct locations.
Excessively long formatting period.
5. If the board fails to function, place the board on a flat surface and seat all socketed components. Gently press each component into the socket.
If your hard drive takes an excessively long period of time to format, it is likely a cable connection problem. However, if your hard drive has a large capacity, it will take a longer time to
format.
6. If you made changes to the BIOS settings, re-enter setup and load the BIOS defaults.
Serial Port
The serial device (modem, printer) doesn’t output anything or is outputting garbled
characters.
1. Make sure that the serial device’s power is turned on and that the device is on-line.
2. Verify that the device is plugged into the correct serial port on the rear of the computer.
3. Verify that the attached serial device works by attaching it to a serial port that is working and configured correctly. If the serial device does not work, either the cable or the serial
device has a problem. If the serial device works, the problem may be due to the onboard I/O
or the address setting.
4. Make sure the COM settings and I/O address are configured correctly.
Keyboard
Nothing happens when a key on the keyboard was pressed.
1. Make sure the keyboard is properly connected.
2. Make sure there are no objects resting on the keyboard and that no keys are pressed during the booting process.
