It's not uncommon for Web browsers to consume a moderate to substantial percentage of your computer's resources, particularly if you're running Flash or Java in one or more tabs. If you notice a CPU spike when you browse certain pages, the pages may contain bugged code, or, in the case of websites like YouTube or Netflix, use extensions that are resource-intensive. If Google Chrome consistently exhibits high CPU usage regardless of your browsing activity, however, and the browser is up-to-date, you may need to disable certain plug-ins or extensions, or reset the application to its default settings.
Method 1 : Use Google Chrome’s inbuilt task manager
1. Right-click the title bar or press "Shift-Esc" to open Task Manager in Google Chrome. Click "CPU" to see which task is consuming the most resources.
2. If you find any of them fluctuating and using too much of your RAM and CPU resources. Chances might be the page is infected or the extension is malfunctioning. Write down the name of the task if it's a plug-in or extension. Select the process and then click "End Process" to close the task and do a thorough scan of your system to remove any malware infection.
