In your case I would try some kernel parameters. They can be changed by:

  1. Use nano to edit /etc/default/grub: sudo nano /etc/default/grub
  2. Add the kernel parameter you want inside the quotes to the line starting GRUB_CMDLINE_LINUX_DEFAULT=
  3. Save the change by pressing CTRL+O together. Then exit with CTRL+X.
  4. Update grub with sudo update-grub

In your case I would test the kernel parameters

mce=off

and

mce=nobootlog
