Why does my Ubuntu 16.10 freeze so often suddenly after a few months?
I have to press the start/ restart button on my machine to reboot the system.
Then it works but after a few minute doing stuff, eg. browsing internet, working on a software, etc it freezes again - everything, keys and mouse and all, stops working!
Any ideas what might be causing this?
How can I check what is going on from my terminal?
Am I being hacked by viruses?
I am using Skull Canyon and it is solely on Ubuntu 16.10 - Kubuntu Plasma 5.8.
EDIT:
A screenshot when it freezes - as you can see that most of the CPUs are reaching 100%!
Why?? It never happened before!

It still freezes as before though...
EDIT 11:
I captured the screenshot when it freezes with top on my terminal. I don't see anything is causing the freeze.
I have upgraded my Kubuntu/ Ubuntu to 17.04. Thought it might fix the issue but it doesn't...

fsck -f /on the terminal, it gives the same warning as in edit 4 above. maybe i have booted it incorrectly? Should i re-format my system instead? Is it a system issue or the hardware issue actually? If it is a software issue, i might have been hacked?
