Yesterday I was working on my computer but it was freezed when I was working. So, I turned off pushing the bottom. When I started again the computer show me a message about the filesystem and I have to run manually fsck. Then I saw some post about it and suggested fsck -yf dev/sda2 for the first time it works. I continued working, but when I realized that I cannot opened google-chrome-browser, after 4 hours I decided to reboot and that was the last time that I saw my desktop.
I tried a few times with the command I mentioned but, sometimes the screen is completely black or purple. Also I tried using the recovery mode, but is same end. What I can do? Is strictly necessarily to make a bootable USB with Ubuntu? By the way, many post said that this a native Ubuntu problem.
More info: I have Ubuntu 18.04, NVIDIA, Intel inside core i7, Asus.
