Some details would help. What version of Windows do you have? What type is the new video card? Was the original card a real card or onboard (part of the motherboard)? What do you mean by "lose video" - the screen goes black or the picture breaks up or something else? What kind of monitor do you have?
Try rebooting in Safe Mode (tap the F8 key while booting) and install the display drivers for your new video card there. Then reboot and see what happens.
