ok i just got the j-pac and the arcadevga. i hooked them up to my cabinet when the pc starts everything looks ok on POST but as soon as window starts loading the screen starts rolling downward pretty fast so i can't read anything.
i tried to start the pc with vga mode and safe mode but i got the same thing, i tried to move the j-pac's jumpers around but i got worst result.
i don't know what to do next please help me!! thanks!
