Hi J Qian,
I am confident that you have a cold solder joint around one or more of the
321pins
that connect the CPU to the motherboard.....a careful inspection with a
magnifying
device may reveal the culprit....as the device heats up, the connection is
made and it work ok.... when it cools down the metals contract and a very
tiny crack opens up
that prevents the system from booting.
Hope this helps,,,and good luck in finding the one that is causing this to
happen!!!
