Dual monitor problems

[sparks]

I have a VisionTek GF2 GTS AGP and an eVGA GF2MX PCI. I am using the Detonator 6.5 drivers. When I first initialize the second video card it works great, I get 2 working monitors. When I reboot, it just hangs on me. I need to go to safe mode, delete the MX from device manager, reboot, reinstall the video and it works again. I just can't shut down or reboot. Any ideas? Thanks!
