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. You may also log onto our ECS website for more information:
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. Make sure the power cord is
plugged into the wall socket & the switch on the Power Supply Unit (PSU) is turned
“ on “ as well. 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.
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
c) The PC suddenly shuts down while booting up.
1. The CPU may experience overheating so it will shutdown to protect itself. Apply
the thermal grease onto the CPU heatsink & ensure the CPU fan is well-connected
with the CPU heatsink. Check if the CPU fan is working properly while the system
is running.

Chapter 5
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
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 components may be at fault.
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.
Maintenance and care tips
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.
5. Check whether there is any bulked up electrolytic capacitor or abnormal
component.
