I have sve15137cn notebook of Sony vaio which has intel 3rd generation i5-3230m processor and onboard (integrated) graphics of intel hd 4000 and amd dedicated graphic adapters.I have installed graphic drivers (v.9.17.10.2817 from sony support website).The drivers have installed successfully but still I can't see intel hd 4000 gpu under graphic adapters in device manager.Under dispay adapters only my amd dedicated adapters are listed.
I have also tried in my bios>advance>intel virtualization technology=enable but nothing happened.
I am now using windows 8 64-bit single language.
So please help me?
