k8n audio abnormality.

[MiranoPoncho]

Ever sience i've booted up, I cannot shake the constant buzzing and humming of the speakers: it matters not weather or not I am using a pair of senheisers, or a highend logitech 5.1/ The result is the same; a whiring. This is almost always present, and intensifies with the use of the hdd. This is on an Msi k8n neo2 and I was wondering how to fix this? Any help would be apprceated.
