Powerpoint crashes far too frequently

According to the article "Diagnose and repair crashing Office programs by using Office Diagnostics", you can run these tests by:

  1. Click the Microsoft Office ButtonButton image, and then click PowerPoint Options.
  2. Click Resources.
  3. Click Diagnose, click Continue, and then click Start Diagnostics.

Apart for this, are there any common properties between the two crashing machines, such as maybe same model of installed printer?
