Windows runs fine Ubuntu freezes randomly

  • 772

I have a dedicated harddisk which I use solely for Ubuntu 16.10.

The computer freezes seemingly randomly (it doesn't appear to be related to running a certain/specific task nor around the same time).

Sometimes it takes an hour to freeze, but it WILL freeze at some point within two days max even if I just leave it there on the desktop without running any task at all.

By "freezing" I mean no keyboard response and the monitor stays on but nothing moves not even the cursor and I have to shutdown the computer by keeping the power button pushed down for a few seconds.

What can I do to troubleshoot this and find what is at fault? like which logs to create (and how to create them) or check?

Thanks.

  1. Launching the top command in a terminal just before the computer crashes, I have noticed a few times that the indicator-datetime process was using 100% of my CPU.

    Solution:
    Therefore I have disabled it from System Settings → Date and Time → Clock tab and un-check Show clock in the menu bar checkbox and now it seems to work fine.

    I have seen similar issues after I had identified this on my PC, both in Ubuntu 16.10 and in much older versions. I also still don't understand why it does it with one of my users, but not with other users on the same computer.
