Ive been trying to get this card to work for a week and I am at my wits end. When I try to boot the computer up with the card in I get white lines on my ACER logo screen and green lines when windows is starting up. After that I lose display, I hear the system start up but no display. I cant start the computer from my old integrated vid card with the new one pluged in so I have no way to play around with the drivers.
try to press F8 at startup and boot to VGA mode.
If that works then try the drivers.
I hate to say this but if changing the drivers doesnt help it could well
be a bad card.
Usually when you start getting lines it is due to bad memory on the card.
