COMSOL Multiphysics crashes silently when modeling. When you try to restart COMSOL it may crash immediately.

Replace any faulty memory cards in your computer that the diagnostics tool might find.
If you are using an older version of Windows you can instead download Windows Memory Diagnostics from here:
