this is my first question here in the forum.
I'm quite ignorant on Linux overall, I am doing my first steps now. I have installed Ubuntu 13.04 on my computer that is a Samsung notebook, I7, 8gb Ram, and Intel sandybridge mobile video device
What is happening is that about every minute the whole system freeze for half a second, then it resumes to normal. An interesting details is that if I am playing music, the music continues to play normally even while everything else is freeze.
The installation is new, I have only installed Heroku, Git and Emacs as far as I recall. I have looked for similar posts and executed several steps, but did not work. In other cases I did not had the knowledge to follow the steps.
I have no clue where to start troubleshooting, can you please guys help me?
