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 installing
any hardware components.
Before Power On
1. Make sure 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 (making sure it is fully seated) and connect the chassis speaker
and the power LED to the motherboard. (Check all jumper settings as well.)
5. Use only the correct type of CMOS onboard battery as recommended by the
Manufacturer. Do not install the onboard battery upside down to avoid pos-
sible explosion.
No Power
1. Make sure no short circuits exist between the motherboard and the chassis.
2. Verify that all jumpers are set to their default positions.
3. Check 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 all the add-on cards and cables.
(Note: By default, the onboard speaker is enabled.)
2. Remove the memory and turn on the system.
3. Use the speaker to determine if any beep codes exist. (Refer to the Appendix for
details on beep codes.) If you've got a no-memory beep code, you will need
to replace the memory modules with new and correct ones, for your system
memory is either bad or incompatible. If you do not have a no-memory beep
code, please call the technical support.
