Appendix B. Troubleshooting Procedures
Use the following procedures and flowchart to troubleshoot your system. If you
have followed all of the procedures below and still need assistance, refer to the
Technical Support Procedures and/or Returning Merchandise for Service
section(s) in this chapter.
Before Power On
Step 1:
Make sure there is no short circuit between the motherboard and chassis.
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 115V/230V switch.
No Power
Step 1:
Make sure the default jumper is on and the CPU is correctly set up.
Step 2:
Turn power switch on and off to test system.
Step 3:
If still not power, turn it off and change the setting on JP26 to short 2-3 pins.
Step 4:
If it does not help by moving the jumper setting, clear the CMOS data.
Step 5:
Check the power supply voltage monitor, specifically, the power supply
115V/230V switch.
No Video
Use the following steps for troubleshooting your system configuration.
Step 1:
If the power is on but you have no video, remove all the add-on cards and cables.
Step 2:
Check for shorted connections, especially under the motherboard.
Step 3:
Check the jumpers’ settings, clock speed, and voltage settings.
Step 4:
Use the speaker to determine if any beep codes exist.
Step 5:
If you are a system integrator, VAR or OEM, a POST diagnostics card is
recommended. For port 80h codes.
Memory Errors
If you encounter a memory error, follow the procedures below.
Step 1:
Check to determine if the DIMM modules are improperly installed.
Step 2:
Determine if different speeds of DIMMs have been installed and verify that the
BIOS setup is configured for the fastest speed of RAM used. It is recommended to
use the same RAM speed for DIMMs in the system.
Step 3:
Check for bad DIMM modules or chips.
Losing the System Setup Configuration
Step 1:
Check the jumper JP26 setting. Ensure that you are using a high quality power
supply. A poor quality power supply may cause the system to lose the CMOS
setup information. Refer to Chapter 2 of this manual for details.
Step 2:
If you still cannot resolve the problem, contact your vendor for repairs.
