Check Your System

Next, you can run sfc/scannow command in the Command Prompt to check your system for errors.

Also, scan your system with a good antivirus software.

And finally, go to Internet Explorer, click Tools, Internet Options, Security, Reset all Zones to Default level.

If these system tweaks didn’t help you, try with some other solution listed below.

Check if certain add-on is causing problems

Maybe some of your add-ons is giving you a problem.

So, run Internet Explorer without add-ons and see if things get any better.

To disable all add-ons in Internet explorer, do the following:

  • open Internet Explorer
  • type about:NoAdd-ons in the search bar.
    This command will open Internet Explorer without any add-ons, toolbars or plug-ins.

If it works fine, then one of your add-ons is obviously causing problems.
