Why is Visual Studio constantly crashing?

Question

Visual Studio randomly crashes when adding/removing references and projects. Any thoughts why? Will installing Sp1 help?

EDIT: I do not work with any addons except S

Answer 1

Most commonly, if Visual Studio is crashing repeatedly, your .suo or .ncb file has become corrupted. Close your project, delete those files, and reopen. This may resolve your problem.

.suo is a hidden file.
