Grounding a computer...?

[003]

I'm trying to spruce up my computer transport setup, surrounding the sound card with ERS paper and the like. I read a lot about computers being bad as a source or transport because they (they, what is they?) are not properly grounded, etc...

That has always confused me. It is plugged into the wall with a grounded cord, and I know for a fact the outlet it is plugged into is grounded.

Heck, ALL computer power cords are grounded! So when it is said they are bad because they are not grounded, WHAT SPECIFICALLY IN THEM is not grounded that causes the problems, and how would I go about grounding it if it is not already?

I have a multimeter, could I use this to determine if it is grounded? If so, how?

Also, are there any other tweaks I could do to the computer and/or sound card to improve coaxial digital output quality?

This has nothing to do with grounding, but it's an awesome read -

"The Art Of Building Computer Transports"

not sure if it's been posted here before...

You can't "ground" a computer. The EMI emitted by the monitor/hard drive/mouse etc will always be there. The only thing you can ground is your device (dac/amp), so try looking into those instead of your computer. Is it a ground-loop issue or is the connectors simply unclean?

I don't have any audible ground loop or any problems I can hear, but I want to make it as good as possible. Is surrounding the sound card with ERS paper the best I can do? Or are there other things I can do physically inside the computer to improve things?
