If it shuts off as described check for a power supply that tests ok but
is NOT compatible with the motherboard. Many high end mobo's need a
power supply that feeds a steady current. The component detection on the
better mobos will shut the board down if it is not the quality tolerance
We just experienced this here two weeks ago with all new components and
the supplier of the components replaced the brand new Power Supply with
a better quality one at their expense and the box works fine now. This
was a mother board that was not cheap. My wife needed to upgrade for
video editing etc. The supplier said they had this problem with several
of the better boards.
