Its odd, with a cd player or laptop it sounds perfect... I think 75% of the problem is with the onboard sound... I dont know anymore in my house with it hooked up to my high end system it sounded good no hard drive activity...

So maybe it is the 5v regulator...

Did you ground your 5V regulator?
No. i guess i could get ground from the chassis of the car instead of both + and - from M1-ATX.

Do you have MSN or AIM?
