Colt141

So, I'm facing some issues with a hardware upgrade on an Alienware M17x-R2 model P01E. I've been attempting to get a GTX 765M OC edition card that I pulled from another Alienware to work fully with the system. As of right now I can only boot the system into Windows 7 through safe mode. What I've done thus far: -Rewrote the INI file to allow Nvidia's drive to install -Flashed the vbios from the original to Kepler Whenever the system tries to boot normally it crashes and the screen changes to a random color, usually pink or black. If anyone could point me in the right direction to making this work that would be great.
