> the creepy thing is if i plug in my head phones, I can hear the sound through the headphones.


Creepy that it happened to you on All Hallow's Evening (October 31).  :Wink:


But, that shows that you have an electrical interference problem, not a mechanical problem (such as the noise from a spinning fan).


If you are using a wireless keyboard and/or mouse, temporarily replace them with "wired" equivalents.


If you have external speakers, move them away from the computer.


If your computer has an external power-supply "brick", move it away from the speakers & the computer.


Are all your plugs (monitor, computer, speakers, printer) plugged into a power-bar, to ensure that the devices have the same "ground" voltage ?


Do you have a router with wireless capability too close to your computer?
