Why does my OS hangs for less than a second?

I use Ubuntu 18.04 with kernel 4.15.0-39-generic.



My system:




  • Intel® Core™ i7-4710HQ CPU @ 2.50GHz × 8

  • 16 GB of RAM

  • NVIDIA 860M

  • Disk is WDC WD10S21X-24R1BT0-SSHD-8GB (03.01A01)


My system hangs for 0.3s to 0.7 second every (mean) 7 minutes. It affects audio, video, program and even CPU interrupts.



My disk S.M.A.R.T. status is OK.



Whenever this happens i get a spike in the CPU chart of System monitor.
The freeze is always followed by the CPU3 spike and is always close to 60% of usage.



There is normally no intensive use and it still happens at the same rate.

          It could be your graphics driver, but more info would be nice. Make sure you're watching the exact time whenever your system hangs. Then, you can check your logs (/var/log/syslog) to see what the issue is. As far as I know, nVidia drivers have been a problem for a while in Linux because nVidia doesn't want to open-source their drivers like AMD. Anyway, if your log at the time it hangs says something like "nouveau" then you can be sure it's a driver issue, so you might want to switch drivers





          EDIT

          Reinstalling GNOME appeared to fix the issue for OP sudo apt-get install --reinstall ubuntu-gnome-desktop
