When videos are played the system randomly freezes to start playing the video, or when it takes a few minutes. It also happens with animations webs. This happened with the previous kernel of 15.10 and with the current kernel of 16.04. The bios is the latest version and use public graphics drivers.
If I do not watch videos or animations I can work full days without freezing.
