Title:
  Random Hard reset

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  The computer hard resets randomly. During the random reset the screen
  goes black, the computer remains on, and then it restarts on its own.
  I see the ubuntu splash screen as it shutsdown. It has been happening
  while opening a file that has been just downloaded in Vivaldi. I
  uninstalled vivaldi (Snap) and reverted to Zen Browser (flatpack). It
  just happened again while saving a file from libreoffice calc.
