Video Card + Latest Norton 360 Update

Since the latest Norton 360 update on 2nd Aug 2017 at 2am my PC has developed problems trying to open Norton 360 if you click on it it displays a circle on the desktop that rotates as if a task is being executed but nothing happens this persists until you hard reset the PC.

Now action taken restored from image 1 week old, run Diskscan, had Nortons Chat tech try to RNR and kill registry and replace and same fault appears if I run Windows Defender and Microsoft Essentials everything works Fine.

PC is a Pentium 4   3.39 Ghz 4GB Ram 32 bit Win 7.1 single use dedicated machine with 250 Gb SSD Video Card is Nividia GeForce 6800 GT Dual 17" Screens.

I am ex tech this has me puzzled after 14 hrs of reinstalling several times and clearing registry etc I can only conclude latest upgrade has an incompatibility with my Video card this has the latest and correct drivers installed.

OK any ideas I like to use Nortons 360 but at present I have uninstalled as can not get to the bottom of this issue.
