The power pack has failed and needs to be replaced, they are easy to change, take the side panel of the tower, there should be 2-3 screws at the back holding in place, the power supply will be in the top corner with a bunch of wires coming out of it, unplug all wires from the motherboard and peripherals inside the pc ensuring you write down where each one goes.
There are 4 screws holding the power supply in place, they are placed at the back of the tower, near the top, undo the screws and the power supply should just pull out of the case, take the power supply to your local store and get a replacement, normally they are priced between ?15-50, put the new one back in the same way and try to boot the pc, it should now be fine.
hope this helps.

Pc not starting When I press power button on cpu


If you are not getting the computer to start up but you are getting the fans to whir for a moment and the keyboard lights to flash, then that means that you probably have a bad motherboard. If you had a bad power supply, most likely none of these secondary indicators would be present. I would advise taking the computer to a local computer repair shop and having a professional investigate the problem. More than likely, he will be able to tell you the cause of your problem in short order.
