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
for details on beep codes.

System Boot Failure

If the system does not display POST or does not respond after the power is turned
on, check the following:
1. Check for any error beep from the motherboard speaker.
•
If there is no error beep, try to turn on the system without DIMM modules. If there
is still no error beep, try to turn on the system again with only one processor in
CPU Socket#1. If there is still no error beep, replace the motherboard.
•
If there are error beeps, clear the CMOS settings by unplugging the power
cord and contracting both pads on the CMOS Clear Jumper (JBT1). (Refer to
Section 3-7 in Chapter 3.)
2. Remove all components from the motherboard, especially the DIMM mod-
ules. Make sure that the system's power is on and memory error beeps are
activated.
3. Turn on the system with only one DIMM module. If the system boots, check
for bad DIMM modules or slots by following the Memory Errors Troubleshoot-
ing procedure in this Chapter.
