5.1 Troubleshooting (How to Get Technical Support?)
5.1.1 Q & A
Q: Do I need to clear the CMOS before I use a new motherboard to assemble my new computer
system?
A: Yes, we highly recommend that you clear the CMOS before installing a new motherboard. Please move
the CMOS jumper from its default 2-3 position to 1-2 for a few seconds, and then back. When you boot
up your system for the first time, follow the instructions in the user's manual to load the optimized
defaults.
Q: If my system hangs when I update the BIOS or set the wrong CPU parameters, what should
I do?
A: Whenever you update the BIOS or if the system hangs due to wrong CPU parameters setting, always
clear CMOS jumper before booting up again.
Q: Why does the system fail to boot up again right after a mechanical power-off?
A: Please keep a 30-second interval between each mechanical power On/Off.
Q: Why does the system fail to boot up and nothing displays on the screen after I did some
over-clocking or non-standard settings inside the BIOS?
A: It should not cause hardware or permanent damage to motherboard when BIOS settings were changed
from default to over-clocking or non-standard status.
We suggest the following three troubleshooting methods to discharge CMOS data, recover the hardware
default status, and then making the motherboard work again. There is no need to bother returning the
motherboard to where you bought it from or go through an RMA process.
Step 1. Switch off the power supply unit and then switch it on again after one minute. If there is no
power-switch on the power supply unit, disconnect its power cord for one minute and then reconnect.
Press and hold the <Insert> key on the keyboard, and press the power-on button to boot up system. If
it works, release the <Insert> key and hit <Del> key to enter the BIOS setup page to apply the correct
settings.
If the situation remains the same, repeat the procedures in Step 1 for three times, or try Step 2.
Step 2. Switch off the power supply unit or disconnect the power cord. Open the chassis cover. Locate
the CCMOS jumper near the button battery. Change the jumper position from default 2-3 to 1-2 for one
minute to discharge the CMOS data, and then put it back to default 2-3 position.
Close the chassis and switch on the power supply unit or plug in the power cord. Press the power-on
button to boot up system. If it works, hit <Del> key to enter the BIOS setup page to do the correct
settings.
If the situation remains the same, try Step 3.
Step 3. The same procedure as Step 2, but while discharging the CMOS data, pull out the ATX power
connectors from motherboard and remove the button battery during CMOS discharge.
Q: How to get a quick response for my request on technical support?
A: Please carry out a simple troubleshooting before sending “Technical Support Form”:
System boot-up fails after the system had been assembled:
Check the motherboard’s supporting specifications first to see if all the key components attached in your
system can meet.
To do so, you may:
ꢀ
Remove all the unnecessary add-on devices (except the CPU, VGA card, DRAM, and Power Supply),
and then reboot.
ꢀ
If the trouble still exists, try another VGA card of different brand/model to see if the system will
start.
ꢀ
ꢀ
If the trouble still exists, try another memory module of different brand/model.
If the trouble still exists, try another CPU and Power Supply.
If the system runs successfully, shut it down and start re-installing the interface cards and devices that
were previously installed in the system. Re-install and start the system one at a time until the system
won’t start.
Malfunction in the OS:
If the system hangs after resuming from S3 or some testing program, if the CPU cannot be recognized
properly, if the display resolution mixed, or if a certain program cannot be executed, etc, you may:
