Ubuntu 16.04 flashplayer causing a hard system freeze

[hogfather]

I've been having an issue where my install of Ubuntu 16.04 LTS encounters hard system freezes when playing flash content.  By hard system freezes I mean that the system locks up, replays the last second of sound and has to be restarted using the reset switch.  

Some points:

 

I have not been able to get anything useful from the system logs when examining them after a crash.

 

The crashes are random. Sometimes they happen twice per day, while other times once per month.

 

I'm using Chrome and have the Hardware Acceleration turned off.

My GPU is a 980Ti using NVIDIA binary driver - version 357.66 from nividia-375 (proprietary).  I gone through a few different revisions (open source: 384.47, 370.28, 378.13, 381.22 and the Nouveau drivers) to no avail.

 

Chrome version is: Version 59.0.3071.115 (Official Build) (64-bit)

 

OS (lsb_release -a) : 
Distributor ID:    Ubuntu
Description:    Ubuntu 16.04.2 LTS
Release:    16.04
Codename:    xenial

 

I've also seen the freeze occur when watching flash content in a VM running Windows 7, which really surprised me. 

Is anyone able to shed some light on this?

I dont use flash player. it is terrible and has a history of insecurity. Most web sites do not require flash anymore. Is it a specific web site that freezes?

I'm using digital TV from my ISP.  Their website is not that up to date, which is kind of limiting.
