There are multiple settings and system bugs that can determine Internet Explorer's bad functionality, but let's focus on the potential solutions. First, try to reset Internet Explorer's settings. Open Internet Explorer, go to Tools, Internet Options, select the Advanced tab, hit Reset, OK and restart Internet Explorer. If after performing this operation, you are still experiencing troubles, try to perform a clean boot, with the help of System Configuration Utility. In order to do that, go to Start, Run and type msconfig. From the General tab, check the Selective Startup box and uncheck the Load Startup items box. Go to Services tab, check the Hide all Microsoft services box, hit Disable all, click OK and Restart now. If after restarting your computer, the problem is still there, you will have to identify which application is causing the error. Open the System Configuration Utility again and go to Services, check the Hide all Microsoft services box and enable the first half of them. Click OK and Restart. Repeat this action for the second part of the list, if the operation is still unsuccessful. After identifying the buggy software, uninstall, reinstall or update the program to avoid further complications.
