A PC that I built 3 years suddenly will not boot up. The symptoms are that when the start button is pressed the the fans turn on for 2 secs and then die. The motherboard light stays on and the PC can no longer be started until the power supply switch is switched off and then on.

This PC was running flawlessly until a couple of weeks ago.

Hi,
you have a problem with your power supply. Might be also a problem with your motherboard but I definately thing it comes from the power supply.

Yes I agree with the guys above,  assuming there is no BIOS beep codes.  Listen carefully when you power up..... if no beeps then it can only be one of a few things.... Bad Power Supply,  Bad Processor, Bad Motherboard (corrupt BIOS), or a dead short somewhere in the system.  Before replacing the PSU,  try removing all non-essential components... such as and PCI Cards, extra memory, any cd or extra hard drives drives (obviously you need your primary hard drive)..... and try to boot again.  I have seen a few occasions when a fried Modem will "short" the entire system and will not allow it to boot,  could very easily be a bad switch too.
    If there are BIOS beep codes,  please let us know.... make model of motherboard,  and the beep pattern you hear.  Good Luck

You should test PSU before rule out the device is fault:

Or use spare PSU and with minimum hardware installed to see what happen.

Thanks all, I will try stripping out the additional sound and VGA card and also disconnect the CD Rom. I forgot to mention this earlier but there is a peculiar smell of overheated/burnt metal.

Will try out the above and update

Yep... with the odor -- its definitely hardware. Start with the PSU... while your case is open, you may wish to inspect the Mobo for bulging capacitors, some years ago certain manufacturers had problems with the electrolyte..
