Computer Not Turning On

Hi everyone,
I recently built my computer, however have not used it because I am awaiting the arrival of a monitor. Yesterday, both the button on the case, and the button on the motherboard worked, however today, it will not turn on. Not even the Power Supply fans spin. Ive checked for any loose cables and tried multiple outlets, and the only thing I hear when I turn it on is a clicking sound and the fans twitch and then nothing. Help!

Corsair HX 750W PSU
ASRock Extreme4 Z77 MOBO
Haf 922 Case

If it matters, the last thing I plugged into it was a medialink USB Bluetooth Adapter.
Thanks.

  4. p.s. dont have anything external in your computer at startup like no cds in drive and nothing that involves usbs or other external ports besides moniters and speakers
  5. oh...the last thing I plugged in before it stopped working was the bluetooth adapter. could that have caused this?
  6. i have mr. debugger and its just blank. also theres no beeps just one clicking sound and then nothing.

    it was working yesterday...do you think it could be damaged since then?
  8. it sounds to me like a psu problem?
  9. Try taking the motherboard out of the case and connect everything up, there may a stand off in the case shorting the motherboard.
  10. I had a very similar problem that occurred with my computer. It frustrated me to no end until I finally figured out it was a short from the external case USB to the USB motherboard pin. Try disconnecting the external case ports from the MoBo and see if that helps.

    didn't help.
  13. Get a paperclip and bend it into "U" shape. take out the power button connector and connect the two pins with the ends of the U, this takes out the chance it is the button that is not working.
  14. problem solved. it was a dead psu. thanks guys!
