Even myself has the same problem as you. Can you please tell me how you solved the problem? In my opinion I think is the video cable from the motherboard to the LCD.
I have the exact same issue. I have done just about everything you have except for the replacement of the hardware. When I was on Windows 7 I had no problems. I just upgraded to Windows 10 and I still have the problem.
The only thing that seems to get rid of it temporarily to continue to use the laptop is to close the lid, which put the system to sleep, and open it up and allow it to wake up.
Even myself i have found two issues that are temporarly solving my issue. One is closing the lid screen for a while and the other is to use the laptop connected with the main supply charger. With this last solution i manage to work and the laptop stops only one times in two hours for example.
I had the exact same issue after updating from Windows 7 to 8 and still experienced it with Windows 10.
I tried different driver versions, checked the cable and even bought a replacement screen cable. Accidentally i stumbled over the solution in the internet (unfortunately can't find the link right now, will edit when I find it).
It's an option in the Intel Graphics Software. You find it under Windows Control Panel, Display, Screen Resolution, Advanced Options, Intel Control for Graphics and Media.
There you activate the advanced settings and navigate to energy. Choose under energy source "Battery" and uncheck "Display-Screenfrequencychange".
(Everything might be called slightly different, I am having German language in the driver.)
This is similar to an issue I've had with Intel graphics that only occurred on battery. For me the issue occurred doing a clean install with the latest drivers.
See if you have any options like this,
1) Goto control panel and open "Intel (R) Graphics and Media".
2) Select the advanced option (this gives all options)
3) Select "Power" menu. 5) Select "On Battery" from the dropdown.
4) Untick the "display refresh rate..." and "display power saving..."
5) Apply the settings And that's it... all seems good so far.
