intel

I've experienced a similar issue, which started to accure after I've updated my PC using windows update. I've then found this thread in the intel community forum. As it seems there is a bug in a driver for Intel UHD Graphics 4600, which is used by at least some of the CPUs which are used inside you notebook model according to my research.

For my CPU there have been no newer drivers solving this issue, but as a workaround I've been able to find a older version of the driver without the bug on the Intel support site. Note that you may should disable automatic driver updates as described here to avoid having the same issue again if this proves to be the problem.
