3. Restart Google Chrome and see if the high CPU usage problem, when running Chrome has resolved. If the problem persists, then disable or – better – remove all the installed extensions and restart Chrome again.

 

Step 3. Create a new Chrome Profile.

1. Close Chrome.
2. Navigate to the below location (according your OS).

A. If you use Windows 10, 8, 7 or Vista navigate to:

  • C:\Users\%Username%\AppData\Local\Google\Chrome\

 

* e.g. If your username is “User1” then the Chrome profile folder "User Data", is stored at "C:\Users\User1\AppData\Local\Google\Chrome\User Data"

B. If you use Windows XP  navigate to:

  • C:\Documents and Settings\\%Username%\Local Settings\Application Data\Google\Chrome\

* e.g. ‘If your username is “User1” then the Chrome profile folder "User Data" is stored at "C:\Documents and Settings\User1\Local Settings\Application Data\Google\Chrome\User Data"

3. Rename the "User Data" folder to "User Data.OLD".

4. Open Google Chrome and check if the problem persists. If Chrome is working properly* and does not cause the CPU to run at high levels, then close Chrome and copy the "Bookmarks" file from the "User Data.OLD\Default" folder to the "User Data\Default\" folder, to restore your bookmarks.

* Note: If Google Chrome still causes the CPU to work at 100%, then completely uninstall and re-install Chrome.
