cant get box on?

This is just a thought.
Have you tested the on/off switch?
Mine developed what is known as a 'Dry joint' on the solder connections at the on/off switch causing a current flow resistance.
The switch itself tested ok.

On advice of electronics engineer re-melted the existing feed in solder joints [un plug from socket!! you'd be supprised how many forget It's still plugged in and live, and boom!!!!.] adding solder if necessary. Re-assmbled and switch on computer and if everyithing came back to life. Job done.
Try it it's a thought, however if you found what cause the problem then post the prob and solution so others can read who may have same or similar probs.

Test power cable from socket to ensure there is no break in the conductors

I asked the repair experts around my area if a fuse exists. They say there isn't one and that the no start up is a problem that they see as 2-3 a week. I was hoping that someone out there knew where/if there is a fuse but the experts say NO FUSE

I TOO HAVE A COMPUTER THAT WON'T TURN ON. I REPLACED THE POWER SUPPLY AFTER I FOUND THAT A CAPACITOR HAD FALLEN OUT. EVEN WITH THE NEW POWER SUPPLY, SELF INSTALLED, IT STILL DOES NOT WORK. A FUSE? OR A TOASTED MOTHER BOARD?
