Internet Explorer has stopped working Internet Explorer

Internet Explorer has stopped working Internet Explorer - When I start IE 7.0.6000 running under Vista, it reports "Internet Explorer has stopped working". This seems to happen around 3-4 times before eventually it works. Subsequently it seems to stop working about 85% of the times I start it. Very annoying.

When trying to view Netflix online streaming videos after the video quality has run and around the buffering time Internet Explorer comes up with the message "Inernet Explorer has stopped working" and then closes down. I've uninstalled and reinstalled and problem still persists. I've called Netflix support and they said it wasnt their problem and gave me Microsofts number. Ive also ran a check of all my plugins and add ons. everything is up to date and seems to be working well. Also when using Firefox on netflix it comes in with a "Silverlight plug-in crashed" I've also uninstalled and re installed silverlight and Firefox, Adobe, Adobe Shockwave, Adobe reader.. not sure whatelse to do. after a problem check this is what comes up
