3-1 Troubleshooting Procedures

Use the following procedures 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.
*Note: Always disconnect the power cord before adding, changing or install-
ing any hardware components.

Before Power On

1. Make sure that there are no short circuits between the motherboard and chas-
sis.
2. Install one CPU (making sure it is fully seated) at a time, connect the chassis
speaker and the power LED to the motherboard. (Check all jumper settings
as well.)
3. Use only the correct type of CMOS battery as recommended by the Manufacturer.
Do not install the battery upside down to avoid possible explosion.

No Power

1. Make sure that there are no short circuits between the motherboard and chas-
sis.
2. Make sure that all jumpers are set to their default positions.
3. Make sure that the 115V/230V switch on the power supply is properly set.
4. Turn the power switch on and off to test the system.
5. The battery on your motherboard may be old. Check to verify that it still supplies
~3VDC. If it does not, replace it with a new one.

No Video

1. If the power is on, but you have no video, remove add-on cards, if possible to
simplify system confi guration.
2. Use the speaker to determine if any beep codes exist. Refer to Appendix A and
Appendix B for details on beep codes.
2a. Check if the onboard video is enabled through Jumper JPG1.
2b. Remove all memory modules to make sure that the system gives alarms
for no memory. If the system beeps, memory modules can be bad or incom-
patible. See Section 2-3 for more information on supported memory.

Losing the System’s Setup Confi guration

1. Make sure that you are using a high quality power supply. A poor quality power
supply may cause the system to lose the CMOS setup. Refer to Section 1-6
for details on recommended power supplies.
