I put it in all the slots I have available and still the same error.the card worked on windows 7 before and I tried both vga and hdmi cords but neither work.
Unless you are dragging your feet on the carpet and shocking things every touch on metal you probably did not fry your graphics card from improper grounding.
Is the card recognized in the operating system?
Did you connect the 6-pin from the power supply to the card?
Is it installed in the proper slot (usually the one closest to the cpu)?
Which connection on the card are you using?
Have you cycled your monitor through all its inputs?
