Check your Power Supply Unit..(PSU) It has most probably "Faulted".

BUT first remove all cards... disconnect all Hard Drives, CD/DVD's etc.. try to power on... if still no-go then ya PSU IS Definitely faulty. Replace.

If it DOES go, then, simply plug in each removed device and turn on again, in turn,... until it will NOT power on & that device, will be your "Faulty" bit.. replace that device/card etc. & NOT the PSU.

The PSU's are fairly inexpensive these days.

To replace ya PSU, open up ya PC... Disconnect the PSU's Plug from Motherboard. Unscrew the Four (4) Screws from PSU, from the rear, near fan.

To install is simply the reverse process... Screw the PSU into place..connect up the Plug onto the Mother Board.. ya done.. Power On.
