I would like to know if you have tried using the drivers directly from the OEM's website.
It is recommended to use the drivers from them since they will include any possible special features for your specific device.
Another option would be to test the system after doing the following; uninstalling the graphic drivers from the device manager, restart and let Windows 10* install the default drivers.
Here you can find the graphics driver for Intel® HD Graphics 520 for 6th Generation Intel® Core™ Processors:
I look forward to your outcome with this.
I used a few ver. of intel drivers each one has been downloaded from official intel site and each one has some bug, these are a results:
-220.127.116.1179 (default installed by windows update) , while using Edge browser i get very often notification that driver has stopped working and during an attempt converting movie from h264 to hevc (by handbrake app)i get blue screen which says something with kernel security, in lenovo solution center i get BSOD either .
- 18.104.22.168.4300 i could say that the result is very similar to previous driver , but seems to have a bit less notification of stopped driver and BSOD occurs in later stage of converting the movie ,also when using lenovo software to check hardware condition(solution center) i get the same BSOD.
-22.214.171.124.4326 (which I'm using recently) I haven't noticed any notification yet , as I remember, but BSOD still occurs in lenovo app , also since now i've not seen black screen bug yet , handbrake works fine.
-126.96.36.199.4352 - there is no any notification or BSOD , but i remember that lenovo app have been showing me error with PCI , there wasn't any problem with handbrake app ,but there is the bug with black screen after short inactivity ,which I think is only one driver ver with the bug.
Notebook is yoga 500.
