When the person passed the laptop to me, I reinstalled ubuntu to start it from scratch. It started well, but along the time it struggled and froze more and more.The best thing you could do with this would be to reinstall the OS
The ACTUAL cause of this problem/s is unknown.
It is highly unlikely that an Update is the cause....if it was the problem would be all over the internet.....and it is not.

I have opened a few laptops before. Could do the cleaning to see if it improves.Sounds to me like the graphics chip may be over heating and failing.
Cleaning out dust and/or replacing thermal pads could help - but not very practical for anyone not familiar with tearing apart laptops. Can you look into the side vents and observe if there is an accumulation of dust?
I have ordered a usb drive. I will create an ISO image as soon as it arrives.It does not sound like a memory issue to me but running MemTest86+ from a "Live" iso or install image would eliminate that question once and for all. I think it is still included on the Linux Mint and possibly Ubuntu Live images.
cpu and mem vary between 50 and 65 for cpu and stable at 37 for mem, user Ludi, command Seamonkey.Definitely NOT.
In Terminal type top and then watch for the highest consumer of %cpu, %mem....the user name is on the left hand side
