No Video
1. If the power is on but you have no video, remove all the add-on cards and cables.
2. Check if memory module population is supported following guidelines on page 31, and
re-seat memory DIMM module(s).
Note: If you are a system integrator, VAR or OEM, a POST diagnostics card is recommended.
System Boot Failure
If the system does not display POST (Power-On-Self-Test) or does not respond after the
power is turned on, check the following:
1. Clear the CMOS settings by unplugging the power cord and contacting both pads on
the CMOS Clear Jumper (JBT1). Refer to chapter 2.8..
2. Remove all components from the motherboard, especially the DIMM modules. Make
sure that system power is on.
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.
Memory Errors
1. Make sure that the DIMM modules are properly and fully installed.
2. Confirm that you are using the correct memory. Also, it is recommended that you use
the same memory type and speed for all DIMMs in the system. See Section 2.4 for
memory details.
3. Check for bad DIMM modules or slots by swapping modules between slots and noting
the results.
4. Check the power supply voltage 115V/230V switch.
When the System Keeps Losing its Setup Configuration
1. Make sure that you are using a high quality power supply. A poor quality power supply
may cause the system to lose the CMOS setup information. Refer to Section 1 for
details on power supplies.
