High CPU usage when using web browsers

Whenever I open up a webpage, my browser uses all 100% of the CPU. The page will run slowly and everything pretty much freezes up. It's happening in all browsers: Chrome, FF and Edge. I'm not sure what to do here. It's a HP laptop running Windows 10.

Seems strange, you mean when you go to task manager (CTRL+ALT+DEL). and check the processes running, the browser  .EXE has all the CPU?  What about the other values like memory, is that at 100% as well. It could be a hardware issue like a failing memory chip causing additional stress on the CPU or if you are using integrated graphics it may put additional stress.

    Open MSCONFIG and try to deselect all unnecessary services other than Microsoft. Next open Services.msc and stop the processes that are not using for long time and disable them other than Microsoft services. Now clear TEMP folder by searching like, %tmp% and it opens the folder and permanently delete all files/folders by pressing CTRL +A. Very few may not be deleted due to background process. Next restart the system & check if that helps.

    Moreover, you can download/install Process Explorer, which is free to use and helps to identify the processes clearly. After installing run any one of browser and then open process explorer and try to identify which processes are running. This is here: https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer
