Troubleshooting Procedures
Use the following procedures to troubleshoot your system.
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.)
No Power
1. Make sure no short circuits exist between the motherboard and the chas-
sis.
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.
