ie is crashing when flash player is enabled. mostly when a video plays on websites

I have flash 20.0.286 for msie installed and enabled.  I get a crash of the "internet explorer has stopped responding" whenever I come across an embedded video on websites. or I try to play a video from the internet.  I have uninstalled it (flash) multiple times and if it is enabled it happens and if disable does not.  I have chrome and am having no issues with it there.

I have windows 7 fully updated.

have reset ie twice

any suggestions would be great at this point.
