System Boot Failure
If the system does not display POST (Power-On-Self-Test) or does not respond after the

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 below.
Memory Errors
1. Make sure that the DIMM modules are properly and fully installed.
2. Con fi rm 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.
Losing the System's Setup Con fi guration
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 1.6 for
details on recommended power supplies.
2. 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.
3. If the above steps do not fi x the setup con fi guration problem, contact your vendor for
repairs.
