I have had to reinstall Win 7 after a disastrous download of Win 10. Now my Alien X51 does not want to see the NVidia card. The Nvidia card was preloaded when I purchased the computer and ran great. I can download updated NVidia drivers but the computer seems to read the Intel HD driver. Any ideas?
Did you download the Alienware drivers first? I've found in the past that you have to do that for the initial install. Then you can use nVidia's drivers after that if you don't do a clean install. Just go to the Dell support site and find your computer model there. Then you can find the Alienware Video drivers designed for the card.
