It look like the problem does lie in the video drivers, I swapped the monitor over to the onboard video (NVIDIA 7050) and it works fine. I have tried two different drivers for the 8400 with no luck. I can't find any older than the the drivers on Nvidia's site and the drivers from Microsoft. If anyone has a dual head card and Windows 7 64bit that works let me know.
EDIT: I did find a site with all the old drivers (guru3d.com), if any work I will post.
