Please help, i have no power going to my pc. It will not switch on at all. I have tried replacing the power supply but that did not work. I have tried the power supply in another pc and it is working fine. I need some advise on what else could be wrong. Please please help.

it is not the plug or the cable i have tested them and the switch at the back is on. i have even tried a new power supply unit in the pc as well

Do you have your motherboard manual handy ? Check this for layout of connectors...It could be the Power switch on front panel of the computer isnt functioning.depending on its age older types switch the power suplies & shouldnt be played with /risk of shock ...however newer types are dc supply from the motherboard &
this can be found by tracing the leads back to the motherboard. under usual operation its a push to momentarily contact switch thats used.If its this type generally cremoving the lead from the motherboard pins & shorting these pins & not the flying lead ones for a moment usually does fire the unit up.If the CPU fan kicks into life then stops Check the Video card to see if its seated properly
