My internet keeps shutting down, with the "Internet explorer needs to shut down" warning t

It only seems to happen when I watch youtube/myspace/veoh videos, go on Neopets, or take quizzes. Same happens when I go into Incredimail, and even Microsoft Word

My internet keeps shutting down, with the "Internet explorer needs to shut down" warning thingy.?

Sounds like a problem with an ActiveX control or something. Click the display details button on the error dialog and see if it says something like "xxxx caused an invalid page fault in xxxx" or similar. Then copy the message down and search on Microsoft.com's knowledge base for a possible fix that may not require re-installation of Word or IE.
