Processor not executing code

This computer has experienced a problem due to the failure of certain code to execute, resulting in a failed
startup of the processor. The issue could be related to the processor or the system board in the computer. If the
processor is socketed, be sure that the processor is seated correctly in the socket. If this error reoccurs, refer to

NOTE: The computer will attempt to notify you of this problem through a series of blinking lights. When you
attempt to turn on the computer from an "Off" or "Hibernated" state, lights associated with the
num lock keys will both blink once followed by a pause, and then continue in a repeating pattern.
