Seems odd that 2 of us have experienced the same exact issue in IE within a few hours.
Not hardly. There are 100s of millions of IE users.
There are many things that can cause a browser to crash. Malware, a bad connection anywhere from your network interface on out. But most problems with IE8 and IE9 are due to a misbehaving or conflicting add-ons - like tool bars, or a bad setting.
If you click on the Start orb, then start typing Internet Explorer in the search box, you should see Internet Explorer (No add-ons) appear. Try that. Or better yet, reset IE by going to Tools > Internet Options > Advanced and click on Reset then see what happens.
Do make sure Windows is fully updated too.
