I am experiencing random freezes in Ubuntu. I went through several fixes proposed (checking nvidia drivers, etc..) but no solution. I bumped into Ubuntu 17.04 Freezing Issue and tried to change the crypttab. I followed the instruction but upon opening with Gedit or nano the file was empty. Could this be the issue?
EDIT: The computer was assembled by me. With:
MSI 1151 Z170A Krait Gaming 3X Motherboard
Intel I7-6700K 1151 Skylake 8MB Cache 4.00 GHz Processor
Crucial Ballistix Sport LT 64GB set 16GBx4 DDR4 2400 288pin whit RAM
Nvidia GeForce GT610
The driver from nvidia I installed is the 340.135 so I am not using the Xorg nouveau stuff.
Also I changed GRUB to include
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"

is better, and if you had set up encryption and didn't add to that file for permanent mount at boot then whatever your issue is might start from there! – George Udosen Sep 05 '17 at 18:48sudo blkid
