[UbuntuGnome] 16.04 and 15.10 locking up

Hi,

I am having an issue with my computer completely locking up. The only way to power down afterwards is to hold the power button down. This was not happening on 15.04. When I upgraded to 15.10 the issue started. I reverted back to 15.04 and never had a chance to look into the issue. The issue has continued to occur with 16.04. I don't seem to have to be doing anything in particular, it happens most often when I am web browsing or watching videos, but that may be because that's what I mainly use the computer for. I did a hard drive test for corrupted sectors but no errors came back.

I'm currently ruing Ubuntu Gnome 16.04 64-bit on a Toshiba Satellite Click 2 L35W-B3204
Intel® Pentium(R) CPU N3530 @ 2.16GHz × 4
Intel® Bay Trail Graphics

Please let me know what other information I can provide to help.

Thanks
