Ubuntu – Random freezing and crashes on 16.04

I'm experiencing very frequent complete system freezes on Ubuntu 16.04 on a Dell 7559 with Intel and Nvidia 960m.

I've tried adding a line to grub found in a previous solution but it didn't work. The problem just started today after no previous issues. It began while using Firefox and then persisted while using Chrome. Also freezes while using other programs, such as WPS Office.

Here's some recent /var/log info from during the most recent freeze. Only way to get system working again seems to be a forced restart.

As I was writing this it also did an unexpected restart.

Any help greatly appreciated.

Cheers
