Chapter 7: Troubleshooting and Support
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 4.
2. Remove all components from the motherboard, especially the DIMM modules.
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.
same memory type and speed for all DIMMs in the system. See Section 3.4 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.
The System Cannot Retain the Setup Conguration
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.
2. The battery on your motherboard may be old. Check to verify that it still supplies
approximately 3VDC. If it does not, replace it with a new one.
3.
When the System Becomes Unstable
A. If the system becomes unstable during or after OS installation, check the following:
1. CPU/BIOS support: Make sure that your CPU is supported and that you have the latest
BIOS installed in your system.
2. Memory support: Make sure that the memory modules are supported by testing the modules
using memtest86 or a similar utility.
