Hi there, I have a problem with my Clevo P170EM and a 8970M. In BIOS screen at the VGA voice it says "empty", i tryed many versions of Win7, Win8.1 but i can't install vga driver, wait i can install driver but for example in gpu-z the fields about shaders ecc ecc are empty or totally wrong and the dedicated vga doesn't work... The only OS i can use is a fu***ng Win8 Pro and the only drivers good for me are the old 14.4 and i have many issues with new games (such as GTA5). Any advice for solve
