So I had gtx 560 and I wanted to change it to 980 I plugged it correctly (I hope) when I start up my computer I can hear the fans working but it uses the onboard graphics card instead. In the device manager I can see my graphics card but.there is a warning sign next to it. I doesnt say the proglem though. In dxdiag the display tab only says n/a. Hdmı is plugged to the card and I installed the driver (the cd didnt work for a reason it said I needed adminstrator rights but I already tried using "run as administrator" still the same problem so I downloaded it from the internet I am nit sure if it is right tho) can anybody help me? Thank you for your time
