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 Appendix A for details on
beep codes.
Note:
If you are a system integrator, VAR or OEM, a POST diagnostics card is recommended.
For I/O port 80h codes, refer to Appendix B.
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.
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.
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 Loses 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 1.5 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.
