Gtx460 graphics card help?

i installed a gtx460 graphics card a while back and now when i start up my computer using the output on the graphics card my monitor says no signal until the point where windows starts. is there any way i can set it so i can see the windows startup screen and bios when using the graphics cards output. (it works on the computers default output)|||youll have to hook it back up to your default output then enter the bios change the video source to pci or auto save and exit then shut it back down change back to the gtx460 and reboot
