NOTES:
If an error message and incorrect audio response occur,
diagnose the error message first.
If you cannot run the diagnostics program tests but did receive
a POST error code, diagnose the POST error message.
If you did not receive any error message, look for a description
of your error symptoms in "Error Symptoms List" in page 79.
Check all power supply voltages, switch, and jumper settings
before you replace the system board. Also check the power
supply voltages if you have a "system no-power" condition.
("Power Supply Cable Connector Specifications" on page 129
If the problem cannot be corrected by using the "BIOS Error
Codes, Messages, And Beeps List" table and "Error Symptoms
List" table, go to "Undetermined Problems" on page 104.
