    Grounding question

    Ok, I am an electrical newb but here goes.

    There is continuity between my -5v on my motherboard and the ground (as tested at the outer shell of the VGA connector) and there is also continuity between the -12v on my Xenarc screen and the outer shell on the VGA connector.

    My question is will there be a problem when a +5 and a +12 v line share the same ground?

    Is there a general rule of thumb I should be following for this kinda stuff?

    Thanks!

    Newer mobo doesn't use -5V. -5V only use on ISA card, and if your mobo has ISA slot, there is problem (I think).

    I have a Single Board Computer that runs on 5V.
