Basically all my computer suffer from this problem. Anyone here know much about it? Antec 900 front panel buzz, read that it is grounded to basically everything, usb, firewire, case... gotta take a look at it. Anyone got any tips on how these things can be grounded correctly? Hmm, I think I got some ideas after typing this... I'll take a look at it tomorrow. Another computer is connected to the TV atm, a ground lift on the tv removes it... but i doubt it is safe... should I just buy some isolation transformers?... theres gotta be a harder but better way to tackle the problem...?
