also i have a Desktop PC with i7-6700k and a nVidia GTX970 Card and Windows 7 Ultimate x64.
I have installed nvidia Driver v368.69 and Intel Driver v4474 and i have no conflict or any Problem.
Which Intel Driver have you installed ?
If you have Optional AntiVirus or Internet Security program, disbale it bevor you install a new GPU Driver.
My G-Data Internet Security has often Problem with Intel Driver and block some files !

The issue seems to be a Hybrid graphics issue; I suggest you to keep using the customized drivers from Clevo manufacturer.
Also, verify if you have the latest BIOS version and chipset driver.
Iigpu suggestion might solve the issue, give a try to it.
Thank you so much for your replies.
So no, i don't have any security program installed, yet.
And Clevo driver for the Intel GPU is the same that Intel has on his webpage.
So the problem should be an that Hybrid graphics issue indeed. And some incompatibility between drivers.
But, I have an another question.
My laptop cpu, an i7 6700HQ, does some electrical noise, like a bzzz bzzzz. This happens even when the laptop is IDLE or when is doing some work, like writing an email, the bzz bzz is clearly audible specially on a quiet room.
Is this noise normal? Should I be worried?
Thank you again
