I know this is an old thread, but I'm having the exact issue as SpeedyBoJangles. I recently purchased a Sager NP9150 which was upgraded from the 670M to a 970M . Problem is that I tried modifying the .inf of the 361.43 driver and the 359.06 driver and the installer detects my card but fails the install after about 30 seconds. I tried disabling driver signing, and Eurocom just gave me the runaround. That leaves me currently stuck on Eurocomm's modded 358.50 driver from last October, and I'd like to be able to run the latest drivers. I'm Prema Mod Bios 1.02.17 PM and the EC is 1.02.11 PM. Could you assist?
