OC Linux began to behave incomprehensibly. How to fix it?

Question

linux

Good afternoon!
OC Linux Mint 17.
Today I turn on the laptop and immediately notice that google chrome has disappeared, installed it on a new one, launched it and everything that I had there, everything was left.
After that, I launched my server-client project (TCP Sockets) in the console and noticed that during actions with files I get errors, that the file is not found or the path is written incorrectly. I launched the same project on the same Ubuntu laptop - the project works fine.
After, when I entered the console mode, I noticed that some obscure hieroglyphs are mixed up in the console instead of full words.
+ when I open nautilus, the directories are displayed with 3 columns, and not 4 as it was.
In the last inclusion, before such nonsense appeared, I did not do anything new and did not install it.
What's going on with Linux anyway? How can I fix this?

Answer 1

It also looks like a problem with the file system (or disks). Restart single and do a fsck.

Answer 2

Sounds like a memory problem.

Answer 3

Yes, it looks like a memory problem, you can check with the memtest utility. I think that this can still happen when the sync call does not work on shutdown - in this case, you need to manually call sync on shutdown and look at the mount options in /etc/fstab, although, as a rule, there is a default delay in Linux for performance improvement. Try echo 'test' > temp_file.txt, then sync, reboot and check if there is such a file. In any case, there can be many reasons, look at the logs. Are you sure you didn't install any updates?

Answer 4

Linux doesn't break down just like that, we look at our latest actions and check ...
