Microprocessor Problem s
During POST, the computer checks the computer's microprocessor and
determines its operational specifications. This information is stored in
system setup. The computer also determines whether one or two
microprocessors are installed, and then verifies whether two installed
microprocessors are identical to ensure proper operation.
Basic Checks:
•Check the diagnostic lights to see if the specific problem is identified.
•If two microprocessors are installed, ensure that they are ide ntical. The
computer may not start or function properly if two microprocessors are
installed that are not identical:
– Different cache sizes
– Different speeds
– Different steppings
– Different types
•If two microprocessors are installed, ensure that a VRM is installed for
each processor.
•If two microprocessors are installed, ensure that the VRMs are
identical. The computer may not start or function properly if two
VRMs are installed that are not identical.
