the hum should go away..
Thanks for your feedback, but even muting everything didn't get rid of the hum. I just tried a couple things and it now seems like a hardware issue...
When the computer was off,
1) I unplugged the power cable to my machine. The hum continued, but when I unplugged the VGA cable, the hum stopped. The hum also stopped when the VGA cable was plugged in, but with no power to the monitor or computer.
2) This led me to believe the monitor was the problem, so I swapped the monitor, plugged it in (still with no power to computer) and the hum stopped.
3) I thought I had solved the problem, so I plugged the power cable back into the computer, and the hum came back.
Obviously, the hum seems to happen whenever there is power connected in some way through my computer. The new monitor must work differently from the old one...
I have tried removing the video card completely from the system, pulling all wires away from the sound card, disabling on-board audio, and adjusting IRQ settings in BIOS.
Is there anything else you can think of?? Thanks
