After a broken usb port made my pc reset, it wouldnt turn on at all. No beeps, lights, anything. I replaced the powersupply and now the lights inside my motherboard turn on, but when i hit the power button the PSU makes a clicking noise and doesnt turn on. Is it possible my motherboards gone? I'm planning on taking it all apart tomorrow and would like some of your advice on what to start looking for.

edit: the usb port that is broken is on the front panel. i unplugged all of it except the power button cables. After that i unplugged everything but the the power cable and still no-dice.

Hi epics

Possible causes may include a system short, incorrect or missing MB connections or indeed a bad MB.

A couple of suggestions I can make would be first remove the MB and do a barebones set-up on a piece of cardboard (make sure it is larger than the MB) only connect the PSU, the GFX card, 1 stick of Ram and the keyboard.
IF your MB doesn`t have a power test switch you will then need to short out the 2 power on pins on the MB header to get the PSU to activate, you can use a small flat bladed screwdriver or a paper clip bent into a U shape, this is perfectly safe if you do not touch anything else, the idea is to see if we can get a BIOS screen if you do you can then add one component at a time until you find the problem component, you must power down and remove the power cord from the wall before adding a component, second suggestion try a known working PSU, it is not unknown for new components to be bad.

Other things worth checking include, if you used stand offs beneath the MB are they in the correct locations (only where there is a screw hole in the MB) otherwise the MB will short out, check for stray screws or bared wires for the same reason, make sure the jumper cap that can be used for clearing the CMOS is not missing or on the wrong pins.
