PC Grounding Problem

\015 I have a very frustrating situation. Which is, I have been unable to resolve a grounding problem which results in a low-pitch humm when I connect my pc to my stereo system using an audio cable. It does NOT occur when I connect my iPod to the stereo using the same cable. There is no humm when I normally play audio on my pc. I have an HP Pavilion (Media edition) and a Pioneer stereo. I connect to the \342\200\234CD\342\200\235 bank on the stereo since that is (presumably) \342\200\234digital\342\200\235. I have sent the signal from the PC to a radio via a wireless FM transmitter and then connected it to the stereo and there is no humm. Therefore, I believe it\342\200\231s a ground fault from the \342\200\234hard-wire\342\200\235 connection. I have done the following:\015\012\015\012\015\012Swapped out sound cards\015\012Connected a grounding wire from the pc tower to the stereo\015\012Connected a grounding wire from the pc to the AC outlet\015\012Connected both the pc and stereo to the same AC outlet\015\012\015\012I am at my wits end. How do I diagnose/solve this issue.\015

\015\012It says it has the 1/8 jack adapter, so it should plug right in!
