I have the new Alienware Quicksilver m17x. It has dual 260m's inside but I'm not using them. I'm stuck with the onboard 9400m. I noticed sli disappeared when "Test Mode" appeared in all four corners of the screen. I have drivers 186.21 installed. The laptops mainly saying that the gpu's are not there. I tried lookin through all the drivers on the site and on disc but no luck. I tried seeing if I can find info online. Nothing. Please help!
