I have heard this comment many times when people find out that I work for the IE team in Redmond. This is especially true when I visit India. One of the quick checks which help to analyze where the problem lies is to run IE without any addons. To do this, go to Start -> All Programs -> Accessories -> System Tools -> Internet Explorer (No Add-ons). If IE runs properly, then this indicates the problem lies with one of the extensions previously installed which is failing to work properly with the new version of the browser. Now you can use Manage Add-ons to zoom in on the faulty add-on and disable it.
