Yes I did, but after that I reinstalled the system because the programs no longer worked
The normal procedure for what you describe in this thread would also be to run fsck to check for disk errors. That this has happened to you multiple times raises questions about your hard drive.
You could reinstall Zorin OS, but I wonder if your drive needs some rather invasive Fault Testing.
I also have these problems on a new HDD
I think it is some incompatibility with some component of my laptop since I took the disk of this and I put it in another older laptop and it turned on without any of these problems

putting the disk in my old laptop turns on without any of these problems or errors or flickering
also the USB with the installer starts without any problem
and in this there are times that the installer does not even finish booting 
Bad sata cable?
Windows works normally
Can it be the video controller?
Perhaps this:
It didn't work
I have had these problems in other laptops where I installed Zorin but they had Nvidia Graphics Cards
But this is integrated graphics, do you know if there is a way to install a proprietary Driver
On the Intel page there is a download of a kernel and Mesa Drivers
What they claim to be compatible with my Skylake CPU
If it's not that, the truth is I don't know what else to do
I find it highly unlikely that the download page for intel would provide anything better than what you have currently. Unlike Nvidia and AMD, Intel is cooperative with Open Source.
When you followed the guide above, did you replace the command for the desktop with
sudo apt install --reinstall zorin-os-desktop
?
No but i will try
I was able to get to the login screen but when I tried to start session the system crashed
You may try a Fresh Re-install... But I still have my doubts about your hard drive.
I did another installation but when logging in the system crashed
Is CSM enabled in your BIOS EFI Settings?
I am using legacy mode

Aside from what we have already checked, I am at a loss. We keep returning to Disk Error, but that may also be a Red Herring. Perhaps others may join in with more helpful posts than I have.
I'm going to see if getting another USB fixes it, I just realized that it is rusty, and I have more than 6 years writing and resetting in it
If it's not that, I'd better go back to Windows because I tried a new HDD I recently bought and it doesn't work either and I haven't used the laptop for weeks 
Wow, that is an Old USB. Yes, they can only handle a limited amount of re-writes.
SOLVES IT 
Buy a new USB and on a live USB run these two commands
sudo badblocks -s -v -n -f / dev / sdb
sudo fsck -cfvr / dev / sda
and ready the system started without any problem
so if it was a problem with my disk
sorry for doubting you Aravisian
