Internet Explorer is Microsoft Window's default Internet browser. If you use Internet Explorern you may experience issues like the browser freezes, hangs up and stops responding. Although many things can cause the browser to stop responding, if the problem persists, you can delete temporary internet files to try to fix this problem.

Click "Start" and select "Control Panel."
Click the "Network and Internet" selection then click on "Internet Options." The Internet Properties dialog box will appear.
Click the "Delete" button beneath the "Browsing history" section. A new window will appear.
Place a check-mark next to "Temporary Internet files" and click "Delete." Allow the computer to delete the temporary internet files then close the Internet Properties dialog box.

If that doesn’t work, you can use Smart Explorer Not Responding Fixer Pro to solve that problem
