Just power on button not working?

[robotuprising]

My computer doesn't start at all (no beeps or anything); however, my motherboard lights up as always and displays the proper code for the computer not being on. Could this be anything else besides the power button on the case being faulty?

Could be a faulty Power Supply or a wiring short. Open the cover and make sure none of the wires are being pinched by any of the covers. Most likely a bad PSU, though.
