[strike][/strike]Its not a ground loop prob because when i unplug the green audio cable there is no buzz. and also it stops if you turn monitor speakers al te way down. ALSO there is no buzz when i plug my headphones into the same port

It's probably 50Hz mains hum. As it's only there with your green cable plugged in and the speaker volume turned up, it's likely your PC PSU has poor filtering. What PSU have you got?
