Hi, i'm kinda desperate with this topic, so i will be very glad if someone can help me. i can't find any official drivers for 6770M in my pavilion DV7. the thing is that my computer has switchable graphic with intel hd 3000 and all the drivers are not designed for this combination. i have some unofficial drivers that i cant remember, but can anyone help where can i get regular site with these kind of drivers or any advice? thank you for help.
