I try to install Win7 x64 drivers but it was doesn't work and then I go its manufacture Site I does not find Intel Graphics Media Accelerator Driver For my OS.
Integrated Intel GMA X4500 graphics. Do you not get any video with the default Windows 8 driver? it looked like ASUS had a windows 7 64 bit driver ver 8.1 and intel had a ver 15.x driver. the driver was pretty old (2009) you might have to install the driver using windows 7 compatibility mode.
