I've been through the problem that even after logging in, after 3-4 minutes RAM memory is being used all of its memory despite I'm not using or running anything at all. For that computer freezes and doesn't respond at all. A couple of days before it was okay. I've noticed it while taking a look at the task manager's graph. I'm running Ubuntu 16.04.2 kernel: 4.4.0-79-generic

EDIT: Output of free -m:

    total        used        free      shared  buff/cache   available
Mem:           2999         559        1454         219         985        2010
Swap:          2859           0        2859

I can't run Startup Applications as before I run it, computer stops responding. And 3GB was enough for me before this problem occured

  • How much RAM do you have at all? Maybe it's less than Ubuntu requires? If it appeared just like this maybe even a part of the RAM hardware died?

  • Please add the output of free -m and top -bo %MEM | head -n 20

  • If I'm not mistaken, 16.04.2 uses kernel 4.8.x. Have you manually manipulated your installed kernels? How much RAM, how much swap? Have you recently added an app to your startup applications? derHugo and RoVo have asked the right questions.

  • @heynnema I didn't manipulate anything really. I can't remember about startup applications. should I upgrade my kernel to 4.8 or 4.9?
