Hiya just built my new pc and makes a weird beeping noise when I turn it off 
Hardware that could make such a random noise is Asus X38 P5E, Antec P182, Fatality X-Fi sound card or Corsair PSU. It only happens when the system is fully off and just want to know if anyone else has it with the above hardware as would be nice to stop it.
