AC Hum problem

[A. Joseph Ross]

Maybe some techies out there can help me with this.

I got a new car radio awhile back, which has a CD player, rather than 
a tape player.  So I decided to record some of my tapes into my 
computer and put them onto CDs.  I got a long patch cord that runs 
from my stereo in the livingroom into my computer in the study, and 
it worked fine last time I used it.

This time, as soon as I connected the patch cord, there was a loud AC 
hum from the computer.  I haven't been able to get rid of it.  It's 
there as long as the stereo is connected to the computer sound card.  
Even if the stereo is turned off.

Anyone have any ideas what's going on and what I can do about it?
