headphone interference

[RickST]

Hi all,
When i plug my headphones into the front jack on my antec 1200 i get a weird clicking interference...

by chance i was talking to a mate about v sync, removed it on wow to show what happened and i got 190 fps and the pitch and freq of the clicks went up

any ideas whats causing it, somthing to do with grafix card perhaps

any help would be appreciated

I had this on my 900. My cable was routed by my graphics card and that was interfering, see if you can move it around so it takes a different path to where it plugs in to the mobo.
