Having problems with your PC Desktops ?

Main power switch does not work. Gateway Model 300S Desktop. I turned it off due to a lightning storm in the area and when I went to restart it, the unit will not start. There does not appear to be power as the light in the on/off switch does not light and the fans, etc., do not start up. There is no attempt to try to boot up. It's just dead. Could it be the on/off switch or power supply? It was working fine until I shut it down.
