Have you tried repairing Office (in case something has happened to the installation)?

Alternatively, since you say you install a lot of programs, the cause might be a poorly designed add-in. Look at the troubleshooting steps for add-ins in the Knowledge Base article at http://support.microsoft.com/kb/921541/en-us/ (How to troubleshoot problems that occur when you start or use Word).
