Re: Dead computer after system shutdown. - Resolved for Now
Box is between two tables but managed to remove side cover and with
mirror confirmed green light on motherboard. Unplugged power cord, green
light goes out, reconnected power, green light on and power switch
works, BIOS message Asus surge protection shut system down because of
unstable power supply..
My records show I assembled this box from components in 2008. Should I
be worried? Expected lifetimes of cpu, mb, power supply?

Where to look for the failure? CPU, motherboard, power supply or
mechanical switch?
I never thought before about how the operating system shuts down the
computer. I know there are two wires from the power supply which the
desktop switch connects to turn on the power supply. How does the
operating system turn it off?
