The first thing I would do is attempt to reinsert the video card again. Pull
out the card gently and then reinsert it into the agp slot. Push it in
gently and using little force. If you need to, push one end in partly and
then the other end. Repeat until the card is fully inserted. Boot up the
computer and see if it was a success. If not, then you can suspect that the
card may be defective or your motherboard may not be compatible with the
card at hand. Usually all motherboards and all video cards are compatitble
with each other. But on very rare occasions you may find a motherboard model
that is very picky about which motherboard it will take. These are usually
the ones that have VIA chipsets. The best way to find out is download a
program called Belarc Advisor that will analyze your computer and give your
everything you ever need to know about your system. Once you do this. You
should find out what your motherboard model is and download the mnaual
online and see what it has to say about choosing and installing video cards.
Otherwise you could just refund the video card and get another one and see
if it works. Good luck! Hope this helps out!
