Thank you for the question. Before you replace the card, have you tried re-seating it? Often times just taking the video card out and putting it back in will do the trick. If it really is the card, the replacement is anywhere between $9.99 and $20 depending on where you get the card from. If that card was suitable for you and you don't have requirements for a better video card, I'd suggest sticking with the same model. If you have any questions I'll be here to answer, just let me know. Thanks again!
