If anyone else is having the same problem, I found a solution.
The animated world on home page is what makes the large CPU usage for me.
What I did was opened task manager (Ctrl + Alt + Del) and select task manager. After that find Google Chrome and expand it using (Right click > Expand) or arrow next to the icon. Find the Google Chrome with largest CPU percentage, right click and end task. After that you should be good to go. I don't know why it does that, if someone knows how to prevent that from happening, please let me know.
