No video output on new graphics card?

I just bought a new Nvidia 7800 AGP card for my system. I installed it, plugged in the power supply, booted it up, and I get no video output whatsoever.

Is there anything else I can try to get this card to work?|||Check that your system has enough power to run the card. Check that you've plugged in the card's external power connector. Try pulling the card out and reseating it.|||Does it have different outputs?, like an S video connector if so try using that, the card might be configured to use the different output and you'll need to change it, but there's not much you can do with no video at all. Also does it have a secondary power connector, some video cards take a lot of power and need a

second connector from the power supply. Or it may just be a bad card. Good luck|||you can try to get the correct driver file if it is showing up in hardware. If it is not even showing up in the hardware list of your computer then just remove and re insert it into the slot and use detect hardware from system menu of control panel.
