I have a darkdawg multi kit that was working, then the hard drive died. I got a replacement installed but now it looks like it is booting, and then it stops on no signal without ever making it to the menu. On that screen with a loading bar there are a bunch of dots in the background that I never noticed before so I'm wondering if the video card has a problem. anyone have any ideas how to get this working again? Ive tried removing and replacing the cards, replaced the coin batteries and reset with the jumper as if it was a new install with no changes
