I have a new agp card which won't work. I suspect the slot to be the culprit. Is there any software that check whether the slot is working proper?ly
The best thing would be to test it with a known working card and to test the card you have right now in a working system. I'm not aware of any software that can test that kind of thing.
Post the specs (as much as possible) here and exactly what the video card isn't doing (work can mean a lot of things=no display, crashing, etc.) Also, what drivers you're using is helpful.
