Since i upgrade from 14.4 to 16.4 my computeur freeze.

I am using à Toshiba C50 19H with "Google chrome stable" each time.

Ubuntu 14.4 was freezing less beacause of it's updates; Now my computeur freeze, every one or two hours aproximatively.

Can someone help me ?

Thank you very much.

Have you tested your RAM using Memtest86 from GRUB?

Thank you for your message :)
I checked my RAM and my SSD and it's ok.

Then I said what about the processor (Pentium N3540 @ 2.16GHz) ? And I found the problem here:

=> Processor is affected by the c-state bug which causes total freezes.

sudo nano /etc/default/grub
Find the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
This needs to be changed to include intel_idle.max_cstate=1
So after your edit it reads:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"

In french:
Si votre Toshiba C50 19H fige avec Ubuntu 16.04 modifier le GRUB comme indiqué plus haut dans ce topic.
