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 that there are no short circuits between the motherboard and chas-
sis.
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.)
No Power
1. Make sure that there are no short circuits between the motherboard and the
chassis.
2. Make sure 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 make sure 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.
2. Use the speaker to determine if any beep codes exist. Refer to the Appendix B
for details on beep codes.
3. Remove all memory modules and turn on the system. (If the alarm is on, check
the specs of the memory, reset the memory or try a different one.)
