THIS IS NOT A CORRECT DISPLAY CARD

I changed out my video card and now I get an error box with the following error message every time I boot up “This is not a correct display card”. I click OK and everything works as it should. I reseated the card, reran the software installation, re-forced plug and play to look at the card again (Diamondmm 770 32MB), but could not get rid of the error box. Any ideas??
