How to fix Ubuntu 18.04LTS freezes?

I've installed latest Ubuntu 18.04.1 LTS about a week ago.

All the soft was installed via system menu or Jetbrains repo.

In 2 days appeared freezes - only mouse moves, irresponsive to keyboard, timer above the window don't tick. For several days it was 1 freeze a day in the evening, then 2 freezes in the evening, yesterday 5 freezes, today - 5 times.

I daily do update/upgrade.

My keyboard don't have SysReq button.

Ctrl+Alt+F2/F3 worked only once, once Ctrl+Alt+ScrollLock added somewhat in appeared console stream.

I googled around and find this post advising to get to /etc/default/grub and changing the default line to GRUB_CMDLINE_LINUX_DEFAULT="noacpi" and then running sudo update-grub.

Then i had my 5 freezes yesterday.
Sometimes after crash Ubuntu asks for sending crash report, sometimes not.

My questions are:

How to get to console and collect info/reason for a crash?

Is it possible to recover from crash without reset or power down button?

How to properly collect info/reason for a crash to send it to Ubuntu
(preferably automatically)?

There is an advice to change kernel in this link.

The kernel in my setup is 4.15.0-39-generic. But it is not in a list of available stable kernels.

Should I change to another kernel in order to get stable system?

Yes, memtest does appear in my GRUB menu. I'll give it a try tonight.
Dual-boot Windows 7 don't show any problems so far.

Just have found quite similar issue with LibreOffice 5.1 / Ubuntu 16.04:

Turned off Java in my LibreOffice, OpenCL already off.
No luck. 3 freezes in 2 hours. Last time touching LibreOffice after a pause freeze everything but mouse again.
Installed NVidia driver v.340.
Let' see.

In terminal do ls -alt /var/crash and ls -al ~/.local/share/gnome-shell/extensions and free -h. Copy/paste that output into your original question. Does memtest appear in your GRUB menu? Report back to @heynnema

@user535733 Updated my post. I did try to investigate /var/log/syslog after some of first freezes. Logging did continue during the freeze. I will try to repeat it later, right after crash.
