Hello Ferdinand, thanks for helping. Unfortunately your suggestion didn’t affect the issue at all. But I’ve discovered that the problems depends on the integrated Intel GPU, since when its driver was uninstalled (before reinstalling it from the Intel website) the computer was working normally. Of course I can’t leave it only with the nVidia GPU since I won’t be able to take advantage of the Optimus power saving technology and I won’t be able to use other operating systems. But I would be very happy if this information triggers your or someone else’s mind
