Verify your slots are correct, don't force the card into a connector.
So everyone can visualize, please tell use the Mobo number and the video card
well, i can't force anything into anything because the video card's "teeth" is facing me not the motherboard i have to hold it in that way because the anchor is on the left if i turned it around it wouldnt work. The video card is nvidia 9400 gt. The motherboard is Gigabyte Ma785gm-us2h.
I had no problem with this card on my old computer that opened from the right which allowed me to put it through the back anchor and the teeth facing the right way.
