    What power supply ARE you using? It has to be something to do with the power supply.
    When I run my PC with an AC/DC ATX PSU, it's perfectly fine...

    That figures!!! Mini-Box PSU...

    Is your M2 grounded to the PC chassis, or mounted in isolation?
    What about the peripherials? Is the HDD isolated or grounded to the chassis?

    I've experimented with grounding everything, and isolating everything...no change...
    However, when I unplug the video, the sound card static is a little less...

    Frank from Mini-Box suggested unplugging the video...
    He mentioned maybe a ground loop or an unbalanced ground?

    Can anyone shed light on this?

    What gauge wire are you running into your M2? Do you feel that it's getting enough current?

    I'm looking at the ATX pinout, and there is only one 12v line on those!
    But four 5V lines and three 3.3V lines!

    I wonder if the PSU isn't supplying enough 12v juice?

    Does the PCI slot run on 12V or 5V?
