Hi,

Is there anything in the logs showing a crash dump?
This might be in /var/log  or wherever your distro stores "pstore" logs.
In ubuntu, systemd puts pstore crash logs in:
/var/lib/systemd/pstore

The crash is probably due to a bug in the Linux kernel, so using the
grub menu to select an old kernel working version might help.
Which kernel version are you using?
uname -a
