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

Hopefully this helps someone. It felt like I had tried everything. I even repaired the installation, which made no difference as well as removed VS entirely and the issue was still there. The log option told me nothing significant, so I eventually deleted all the bin and obj folders in my solution as well as all the .suo and .user files and moved it to a completely different folder off the root folder on my harddrive and rebuilt it. It magically came right!
