I recently deleted windows and installed Ubuntu 17.04 on my laptop Acer Aspire e 15. Everything was fine the 1st day. I set up everything, installed some programs, adjusted some settings.

On the second day the system started to freeze. I can't use my laptop for more than 10 minutes without it freezing. I can't move the mouse or use the keyboard and I have to force shutdown.

I tried a solution I found to edit the file /etc/default/grub but it didn't work.

What else can I try?

Here is the syslog file. The system crashed 22:24:48

    what did you do to /etc/default/grub? This System freezes completely with Intel Bay Trail? If it's not a Bay Trail processor, that won't work. I think you need to tell us your graphics card and CPU. – Zanna Aug 28 '17 at 16:31

    First you need to identify your hardware, could be anything from a poor graphics driver to a bad hard drive to a bad wireless driver. Second you need to describe what you mean by "adjusted some settings" . Third sounds as if you may be making things worse, what and why are you editing /etc/default/grub ? To what end and why ? – Panther Aug 28 '17 at 16:34
  • i edited file and changed GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1" – TOnyMontana Aug 28 '17 at 16:40
  • and did you run sudo update-grub after doing so? – Zanna Aug 28 '17 at 16:49
  • About my hardware: 8GB RAM - AMD DUAL CORE A9-9410 UP TO 3.5GHZ - AMD RADEON R5 M430 2GB – TOnyMontana Aug 28 '17 at 16:49
