[Internet Explorer error: "internet explorer has stopped working"]

I am running 64 bit Windows 7 Ultimate and regularly get an error messgae saying "internet explorer has stopped working" and is closing that program. I'm not sure, but I think I am running internet explorer 8 as my default browser. Any ideas on what might be causing this and the necessary corrective measures needed ? Thank you.....rocknroller

Just as I posted this message, another error popped up saying that there was a connection proble and asked if I wanted to diagnose the problem. I have used this feature before and have never gotten any results. The message always comes back saying that windows cannot determine the problem so I have to use the back button to get to a workablr screen,

 

Thanks Evan.....will do......rocknroller...

 

Due to some java scripts issues and its running sometimes this message appears on IE8. I see this message many times even when i log on to my facebook website. But on refreshing the page, it gets fixed. There must be some add-ons missing which are now included in IE9 so as Evan Omo suggested, upgrade to IE9 and hopefully you won't see such messages again.
