Don't have access to your docs in google. Must of all my friends here have the same settings as I do.
I do see that HD 4000 is not offically supported under Windows 8. It talks about WDDM is limited to version 1.1.
The latest Windows 8 driver is WDDM 1.2, so this could be your issue.
So you might want to un-install 13.1 and install 12.6 which is the last supported version I could find.
It seems that video cards no matter how good they are beginning to have a shorter and shorter life for support with newer O/S.
My older boxes with XP and AGP cards are just going to scrap next April.
