There are many IE's. Do other browsers work?

The fastest way to determine if an add-on is causing the problem is to run IE7 with no add-ons.
You can do this by going to Start, clicking All Programs, click Accessories, click System Tools and click Internet Explorer (No add-ons).
This disables all add-ons from loading in that instance of Internet Explorer. If the problem goes away, you can manually disable specific add-ons to find the specific one causing the problem.
