Just installed Carpc, and touchscreen. I found out that when engine is on, whining comes along from the speakers. Did some research and found that touchscreen LCD is the one making the noise. Whining gets louder when RPM gets bigger, so my question is, how can I ground my touchscreen? Power for the screen comes from the cigarette adapter plugin, and screen is connected to the computer with USB and VGA.
Any ideas?

EDIT:
Oh, sorry about the bad explanation.. laptops audiocable is connected to connect2box, which is connected to my cars head unit (cd charger). It makes AUX-IN connection possible.
So the sound is coming from the car speakers. Screens speakers are not connected at all. More ideas?
