For some time my pc case was getting very hot. I turned it off and let it
cool down and then resumed. Yes I know I should have done something about it
then. Alas , last week it shut down never to start again. When I plug it in
and press the start button , no response , not a gig out of it!!!. However
on the mother board a small red pilot llike light is on. Is it the cpu or
the power supply unit or the mother board ??? .
