You’ve started your PC in Safe Mode before, now start your Internet Explorer 9Â browser in Safe Mode. Here is how you do it:
Hit the Windows button on your keyboard or click it with your mouse. Open up Start Search and type “iexplore -extoff” and click Enter on your keyboard.
That should open up Internet Explorer without all the addons and browser helper objects and whatnot, allowing you to go into the Addons section and disable the one which you think may be interfering with IE. This tip should work with all versions of Internet Explorer like IE 8, IE 10, etc.
Good luck!
