My laptop is Sony Vaio VGN_NR38S and it has a nvidia Geforce 8400M GT gpu in it. This gpu got malfunctioned, the screen went black with various colors of stripes. So I figured the gpu is broken and uninstall the nvidia driver. Now it shows the actual screen (though i don't know if it is the Intel integrated gpu as the Device Manager doesn't show even the Display option), but I dont know if any Intel Graphics driver is needed to be installed. I can now use the laptop in 1280*800 (which is the screen size) resolution but can't properly run any video files with more than or equal 720p.
So my question is, do I need to install any Intel graphics driver? If yes, then which one?
