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.
Always disconnect the AC power cord before adding, changing or installing any
hardware components.
Before Power On
Make sure that the 8-pin 12v power connector is connected.
Make sure that there are no short circuits between the motherboard and
chassis.
Disconnect all ribbon/wire cables from the motherboard, including those for
the keyboard and mouse.
Remove all add-on cards. Install a CPU and heatsink (making sure that it is
fully seated) and then, connect the chassis speaker and the power LED to
the motherboard.
Check all jumper settings as well. Make sure to use the correct type of CMOS
battery as specifi ed by the Manufacturer.

No Power
Make sure that there are no short circuits between the motherboard and the
chassis.
Make sure that all jumpers are set to their default positions.
Check if the 115V/230V switch on the power supply is properly set. Turn the
power switch on and off to test the system.
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
If the power is on, but you have no video--in this case, you will need to remove
all the add-on cards and cables fi rst.
Use the speaker to determine if any beep codes exist. (Refer to Appendix
A for details on beep codes.)
Remove all memory modules and turn on the system. (If the alarm is on,
check the specifi cations of memory modules, reset the memory or try dif-
ferent modules.)
