hello, I have a problem and I need help, I have a clevo p170em with a radeon HD 7970M card, the card burned and I ended up getting another one gtx 485m. however this board was to an earlier model to my windows and does not accept the driver of it. I wonder if posivel make any changes in the bios or if you have any nvidia driver for this card that works in clevo p170em.I am desperate because I need the card to work and do not have to buy another one now.
