This just started happening yesterday. I didn’t knowingly change anything although I have auto-update enabled in Ubuntu.
I can start chrome fine, it will work for a while, but then I open a tab and it will freeze everything except the mouse which I can still move around. I can't do anything (including switching to ctrl-alt-fX) so only option is to REISUB (or hard-reset). Restarting chrome after a while usually has the same effect as opening a tab.
I tried completely purging chrome and removing the settings folder before reinstalling latest version but it didn’t help. Disabling all extensions didn't help.
I'm running latest stable Ubuntu 14. 15gb ram, intel i7
Another oddity is the little notification windows I get from chrome, which would usually show info about a new email or any of the plugin notifications, it's now just a black block, no content.
Is there a log I can look in to find something about the crash? I checked dmesg but it doesn’t mean much to me:

I have not tested chromium, I have read that similar happens in that one. Other topics I have read suggest switching to Firefox or chromium but that Isn't solving the problem. I need chrome for numerous work reasons and as it works just fine at home on same Ubuntu version so logic would suggest that it is fixable.
I think it's more linked to the duration chrome has been running and not ubuntu. If I start Ubuntu and launch chrome right away it will crash on a new tab after a few minutes. If i don't start chrome after booting and only start it later it will launch fine then crash after its been running for the same few minutes.
Many thanks
