Drivers don't work that way. You can't use an Nvidia driver with Intel graphics just because you want to. You use Intel drivers with Intel graphics, Nvidia drivers with Nvidia graphics, AMD drivers with AMD graphics, etc. Trying to install the wrong driver will give you just the results you are experiencing.
I think the correct way to fix this is to install the Intel HD driver and then clean install the nvidia driver second
Also, if you have switchable graphic memory, then it shows only the integrated graphic in DxDiag.
If still issue persist, this could be a hardware issue. Please visit the nearest Lenovo authorised service center for hardware assistance.
I hope the above information helps.

3 month ago i posted the same issue with graphic driver problem: https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Lenovo-Y70-Display-driver-Intel-HD-graphics-dri...
still waiting for someone to explain what to do, you are giving us just general options what to do and no solution, meanwhile my laptop was on service twice from that time, and they said to me, that everything works fine, because they only test it, like i do, and on the test always seems fine.... so i'm still waiting
