So here is the deal; after weeks of "please install w10" spam i finally caved in an installed w10 on my Alienware laptop m17x. After doing so, my computer forgot about the Nvidia card installed and no matter what i tried it wouldn't detect the GPU. So i used the regret button and went back to my original w7 setup, but my problem followed me and still it cant detect my Nvidia GPU. I tried to install and reinsall the GeForce Explorer, but nothing. Any suggestions please?
