Troubleshooting Procedures

Use the following procedures for troubleshooting. If you have followed all of the
procedures below and still need assistance, contact your vendor or our Technical
Support staff.
NOTE: Before the over-click action, please make a system boot-up disk
that includes awdflash.exe and BIOS file, and add awdflash
xxxxxxxx.bin/sn/py/cc/r to autoexec.bat. on the disk. If over
clocking fails, the system will not be able to reboot and the floppy
disk drive may appear to be in action. When so occurs, insert the
disk mentioned above into the disk drive, and your computer will
shut down and successfully reboot on its own.
As the CPU is from over-clock to crashed status, please refer to the steps as
below:
Step 1: Power off the computer, and then remove the power cord.
Step 2: After one minute, plug the power cord back in.
Step 3: Press the "Insert" key before rebooting the mainboard power. Then
CPU will turn back to safety status.
When the floppy disk drive is working, but there is no video shown on the
screen -- there are two reasons may cause this situation:
1. As you operate AWDFLASH, the system is power off.
2. Sometimes this situation will happen--the CPU crashes from over-clocking.
In this time, you must follow the following steps to deal with it:
Step 1: Insert the boot-up disk of Note we mentioned above into the disk drive.
Step 2: Reboot your computer.
Before Power On
Step 1: Make sure there is no short circuit between the motherboard and case.
Step 2: Disconnect all the ribbon/wire cables from the motherboard.
Step 3: Remove all the add-on cards except the video graphics card (Make sure
the video/graphics card is inserted properly).
Step 4: Install a CPU, the chassis speaker and the power LED to the
motherboard (Check all the jumper settings as well).
Step 5: Install a memory module into one bank.
Step 6: Check the power supply voltage monitor 115 V/230 V switch.
No Power
Step 1: Make sure the default jumper is on and the CPU is correctly set up.
Step 2: Turn the power switch on and off to test system.
Step 3: If there's still no power, turn it off and check change the jumper setting
again.
Step 4: If it does not help by changing the jumper setting, clear the CMOS data.
