  • Pause any Chrome downloads
  • Quit any unnecessary programs running on the computer. Press Shift and Esc to open the Task Manager. This lets you see the largest memory users so you can quit them.
  • Close your browser down occasionally if you want to stop it from using too much memory. Right-click the taskbar and choose Task Manager. Choose your browser from the list and hit End Task.
