faulty power supply,.... would be my guess
quite cheap replacement, and easy to check, whip the back off, find a connector that has: red, black ,black and yellow, and look for 12v and 5v, if
that's there as it should be then it might be more serious, but if not, then it's a £20ish fix

Sounds like the PSU has given up the ghost. Has it overheated due to dust build-up?
Cheers,

When thinking outside the box doesn't work any more, it's time to build a new box

Does sound failed power supplyey. If you haven't already tried it, switch it off fully at the wall for 10 seconds or so, then try again.
Sometimes if a power supply shuts itself down due to some fault it needs a 'proper' power cycle before it'll start up again.

this worked on my mates pc, so worth a try. not sure what make his is though, not even sure he knows.
anyway, unplug pc from the wall, press power supply button for 1 full minute, time it to make sure you're not short of a minute, plug in and try
again.
can't remember what his mother board is, i didn see the books for it at one time.
worth a shot since its free?

Either a short somewhere or the PSU
Short could be a loose screw rattling about in the case or a wire trapped.

Yup. Capacitor cancer in the PSU no doubt
Had the same in the PSU of one of our LED screens at work. The little shits wanted to charge £250 to come and change it and charge £250 (-vat) for the
"quality PSU" which infact turned out to be a £20 switched mode power supply when I opened up it up. Bulging caps quickly confirmed. For
£20 I couldn't be arsed to get out the soldering iron so a quick Ebay purchase and two days later it was fixed. £500+ saving. Still, if there
are fools out there who will hand over £600 odd quid to replace a sub-standard part.....

heres a simple check thats usually pretty accurate
in a quiet place put your ear to the psu and plug the power cable in
you should hear a small 'crack' as the psu gets power (im sure there is a scientific term)
if you hear the crack, i would say the psu is fine
no crack, dead psu.
if its got a couple of hard disks and no major gaming hardware buy a cheapo one for £30, 300W should be more than enough.

girlfriends brother had blown PSU on his PC.
Machine was totalled as failing PSU caused a spike and burnt out all "usable" parts including valuable data on hard drive.
if you are lucky and no other hardware damaged, take it as a lesson "well learnt" and back up irreplaceable data!!!
nothing is impossible
everything is possible
