2. Set all jumpers to their default positions.
3. Power up. If the system boots, check for memory errors and add-on card problems.
No Power to the System
• Check that the power LED on the motherboard is on.
• Make sure AC power is being supplied to the power supply.
• Check that the power cord is plugged into a power outlet that supply 100-240V, 60-50Hz,
8-4A.
• Turn the power switch on and off to test the system.
No Video
1. If the power is on, but you have no video, remove all add-on cards and cables.
2. Use the speaker to determine if any beep codes are present. Refer to Appendix A for
details on beep codes.
3. Remove all memory modules and turn on the system (if the alarm is on, check the specs
of memory modules, reset the memory or try a different one).
System Boot Failure
If the system does not display Power-On-Self-Test (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 installed. 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
contacting both pads on the CMOS clear jumper (JBT1). Refer to Clear CMOS in Chapter 2.
2. Remove all components from the motherboard, especially the DIMM modules. Make sure
that system power is on and that memory error beeps are activated.
3. Turn on the system with only one DIMM module installed. If the system boots, check for
bad DIMM modules or slots by following the Memory Errors Troubleshooting procedure in
this chapter.
