|Install '''THERMAL''' grease on the processor||Use only enough thermal grease on the top surface of the processor to provide a thin film coating. Yes, I said '''TOP''' surface...putting grease on the pins of the processor generates a large quantity of laughter and endless chastisement from your co-workers. The thermal grease film provides a more efficient transfer of heat from the processor to the heatsink. Applying too much thermal grease defeats the purpose and, instead, becomes a thermal '''barrier''' that traps heat in the CPU causing premature failure. | |Install '''THERMAL''' grease on the processor||Use only enough thermal grease on the top surface of the processor to provide a thin film coating.

There are a multitude of items to check in motherboard testing..
NOTESReasons NOT to reject a motherboard on preliminary inspection
Motherboards GENERALLY have a standardized layout as follows:
