OK Jim, yes it is a graphics card, I have looked it up, the two plugs, you pulled them off the graphics card yes? if so they should either be different and one won't plug into the others socket, or they are the same, if they are the same it shouldn't matter which way round they go. Do the cables go directly to the power supply or to the mother board?
If we can get the graphics card back up and running OK, we stand a chance with the sound, which I think may not actually be connected to the graphics card, and will still be on board or via a separate sound card.
Let us know what you find in the sound, video and game controllers once it is working.
