I don't know where else to turn, I know this site is about hardware but I need assistance is this is the only place I have left. My Alienware M18x r2 (it was a gift, would have rather built a computer myself) had its initial GPU, the Nvidia 660m, fry and was replaced by a 770m. Problem, the 770m is from another laptop, So to I can't go through the typical route of installing the latest driver, I need a modified one. I can't modify the driver myself, as I am ill equipped with the necessary knowledge of such acts. I don't know where the part came from, it was apparently a spare over at the Parts People (Dell Computer Repair Service). Someone, please help me.
