Power Problem

My computer I just built isn't powering up for some reason.
I've checked:

1. Both ATX supplies are plugged in.
2. Power Switch is in right spot on mobo.
3. Recessed switch is at 115V
4. Switch is on I


Anyone help?
 
Is the switch supposed to be set to 115V? If you live in Australia or Europe it's supposed to be set to 230V or else the PSU will be damaged.

Assuming the voltage setting is correct, I would look for a short between the mobo and case, especially at one of the mounting holes (may need 1-2 fiber insulator washers on some holes) or the corners (inadequate support can cause mobo to bend enough to touch the case). Also it's really easy for AGP cards to become unseated, even from the rear of the case flexing.
 
I think that's what happened. The motherboard was bending slightly to the right and the top corner was touching the metal.
 
remove the CMOS battery for 5 minutes then replace it
check the surge protector or outlet (some surge protectors have individual fuses to outlets)
swap out the power supply with another

in the void the warranty category
pop the top of the PSU and look for blown fuses


what is the supply and what is it powering?
it could be simply overloaded and have blown a fuse to protect the board (if your lucky, if not it could have took stuff with it)
