Many Internet Explorer users notice that their computer slows down considerably when the browser is active. In most cases, the problem is due to browser options that require high CPU usage. By streamlining your Internet Explorer setup and removing options that cause slowdowns, you can improve your overall computer experience.
1 Smooth Scrolling
According to Microsoft Support, Internet Explorer comes with a smooth scrolling feature that can cause the CPU usage to spike to 100 percent while you scroll. To disable the option, open the "Tools" menu, choose "Internet Options," select the "Advanced" tab and uncheck the box next to "Use smooth scrolling."
2 Service Pack
Occasionally, Internet Explorer will use a high percentage of your CPU power when it encounters a 404 error code. To solve the problem, Microsoft recommends that you install the latest service pack for your operating system.
3 Corrupt Profiles
If your user profile is corrupt, the Csrss.exe file may cause Internet Explorer to use a great deal of CPU power when you right-click on an item. If that is the case, you will need to back up your files, delete your current profile, and log off of Windows. When you log back in, your computer will automatically create a new profile.
