NOTE: To diagnose a problem, first find the BIOS error messages, codes, or beeps in left column.
If directed to a check procedure, replace the FRU indicated in the check procedure.
If no check procedure is indicated, the first Action/FRU listed in right column is the most likely cause.
NOTE: Normally, the processor fan should be operative, and the processor clock setting
should be exactly set to match its speed requirement before diagnosing any processor problems.
