I'm not the strongest electrically, but when I've run into noise issues, it was either we did something obvious and we were able to fix it (like in the non-grounded lathe example from Marius Liebenberg) or we never found the problem. We put on all kinds of ferrite torrids and inline filters and they didn't do squat. While they may work, I'm skeptical.
I think you said your issue was windows start to open and you get weird behavior on the screen, it seems to be mouse, keyboard, or pc noise. I see a large 'wall wart' power supply that I'm assuming is powering the PC? Maybe I missed the other PC power supply, but those wall warts are usually un-grounded, so maybe try a standard PC power supply w/ a ground on the power cord and to the PC. Another thing to try might be how you have the Mesa card powered, I'm not sure what Mesa board you have, but the 7i77 has jumpers for 5Vdc and you can power from the PC or externally. Maybe you've got noise on that 5V rail back through the PC? Lastly, running the mouse or keyboard cable near a power cable, especially a noisy one, could cause what you're seeing. I think you tried this one already.
