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 removing any hardware components.
Before Power On
1. Make sure that no short circuits exist between the motherboard and
chassis.
2. Disconnect all ribbon/wire cables from the motherboard, including those
for the keyboard and mouse.
3. Remove all add-on cards.
4. Install one CPU in socket#1 (making sure it is fully seated) and connect
the chassis speaker and the power LED to the motherboard. (Be sure
to check all jumper settings as well.)
5. Make sure to use the correct type of onboard CMOS battery as recom-
mended by the Manufacturer. Do not install the onboard battery upside
down to avoid possible explosion.
No Power
1. Make sure that no short circuits exist between the motherboard and the
chassis.
2. Verify 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--in this case, please first
remove all the add-on cards and cables.
2. Use the speaker to determine if any beep codes exist. Refer to the
Appendix for details on beep codes.
