Hello everyone! I need some help with installation of a graphic card in my Alienware (M18 xR2) laptop. Before the one mentioned I had another graphic cards, Radeon HD7970m Crossfire. One of the cards stopped working and I bought a GTX970m and now, IO have a problem installing a graphic driver. During the installation the screen turns black. After putting the computer in sleep mode and while awekening it, in manager device there's a yellow triangle with an exclamation mark. My Bios is A11 from DELLS's official website. I downloaded the graphic drive from a site called Eurocom. I wanted to download a modded bios from this very website but I can't because it says that I have no permission. I need help with going through this problem.
