Check task manager and ensure there is nothing in there which prompts this behavior. Or check the power options.
You can use a clean boot to find if another program running at the same time as Internet Explorer is causing this to happen. A clean boot with only load Microsoft processes, and allow you to identify which process is causing the problem.
- Click Start
- Type msconfig into the search field
- Press Enter on your keyboard
- Click Continue on the User Account Control (If prompted)
- Click Selective startup
- Uncheck Load startup items
- Click the Services tab
- Check the Hide all Microsoft services box
- Click Disable all
- Click OK
- Click Restart Now
Once your computer has finished restarting, test to see if you still get the same problem in Internet Explorer. If not then you just have to identify which service/startup item was causing the problem.
- Click Start
- Type msconfig into the search field
- Press Enter on your keyboard
- Click Continue on the User Account Control (If prompted)
- Click the Services tab
- Check the Hide all Microsoft services box
- Check (Enable) the top half of the service boxes
- Click OK
- Click Restart Now
Once your computer has restarted, again test to see if the problem is still gone. If so, then the services you enabled are good to stay. Repeat the enabling process for half of the remaining disabled services and continue this process until the problem returns or all services are enabled. If the problem returns then you will need to test the last batch of services you enabled one by one to find which was causing the problem to occur.
If you enable all services and the problem still hasn’t returned:
- Click Start
- Type msconfig into the search field
- Press Enter on your keyboard
- Click Continue on the User Account Control (If prompted)
- Click the Startup tab
- Check (Enable) the top half of the service boxes
- Click OK
- Click Restart Now
Follow the same process as before, with testing after each restart. If the problem hasn’t returned, go back and enable half of the remaining list of startup items and continue the process until the problem has returned. Then you will need to test the last batch of startup items you enabled one by one to find which causes the problem to occur.
Once you have identified which service/startup item causes the problem in Internet Explorer you will need to either disable/uninstall/update the program to avoid further problems.
