I seem to be running into an issue with my screen, i have the car running and i boot the computer and i get white horizontal lines on the screen, sometimes seems random other times seem to go faster when the car moves faster. It also only happens on top portion of screen. Then slowly after some time the screen itself starts to get brighter and brighter. I dont know what it is, i took apart the vga connection to comptuer, still happening. I fiddled with the ground and power cable, no reaction to screen.
This whole thing is soo random, because i had it working b4 i connected it to computer. It was connected to my digital camera and it was working, flawlessly. Now I am lost confused and ****ed.

HELP ME!!!!!!!!!!!!
