Hey thanks for the reply. I too managed to solve my issue as well. I had the motherboard in a wooden case that I had built. So after much troubleshooting, i cut a piece of metal out of a computer case that was motherboard-sized and put in in the box like so:
Motherboard-->Metal Standoffs-->Metal Case Piece-->Wood Box
I then made a ground with an 8 gauge wire hooked up to an "O" ring connector and put that O ring inbetween the screw in the motherboard and the standoff of the metal piece of the case, therefore grounding the entire motherboard to the car. Guess what? worked like a charm! I now have nearly no noise at all, and the lines on my monitor have vanished! I have yet to take it out driving and see if the engine whine is gone however...lol
The logic was that a normal computer is connected to the case via metal standoffs. The entire case is then grounded to the wall because there is a ground pin on power cords, and that ground makes its way through the motherboards ground points. ok, that probably doesnt make sense in words, but it solved my problem :dance:
And btw, i have a pioneer 300 watt 4 channel amp, so I think im good :)
Thanks for the reply to an older thread though!
