Freeze Screen

[alfred]

 I am "just" surfing the internet(not running other app) with Chromium and suddenly it freezes.
No keyboard or mouse response the only option shutdown button.
My laptop it's an HP Pavillon x360, before the upgrade I was using Ubuntu14.04 and I never had this kind of freezes.
I Just upgraded to Ubuntu 16.04 (previously 15.04 as recommended) and I doesn't make other change (software or hardware)
The two days I am using ubuntu 16.04 I get the same error.
