"Whoa! Google Chrome has crashed."

Issue
This error displays when Google Chrome unexpectedly shuts down.

Solutions:


Solution 1:
Try restarting the browser.Whenever possible, Google Chrome will restore webpages from your previous browsing session.

Solution 2 :
Do you have Internet Download Manager installed?If you have Internet Download Manager installed, update to IDM version 6.03 Beta or disable the "Advanced browser integration" option by going to Options > General in Internet Download Manager.

Solution 3 :
Check whether you need a new browser user profile.If you see this error message repeatedly, your browser user profile may be corrupted. First try moving the Default subfolder from your User Data folder to see if that fixes the problem:

1. Go to Start menu > Run.
2. Enter one of the following directories in the text field, depending on your operating system:Windows
   
   
   • Windows XP: %USERPROFILE%\Local Settings\Application Data\Google\Chrome\User Data\
   • Windows Vista and Windows 7: %LOCALAPPDATA%\Google\Chrome\User Data\
   Mac OS X: ~/Library/Application Support/Google/Chrome/Default
   
   Linux: ~/.config/google-chrome/Default
   
3. Click OK.
4. In the window that opens, rename the "Default" folder as "Backup."
5. Move the "Backup" folder from the "User Data" folder up one level to the "Chrome" folder.

Solution 4 :
Check for problems with protected system files.

1. Go to Start menu > Run.
2. Enter the following: SFC.EXE /SCANNOW (make sure there is a space between SFC.EXE and /SCANNOW). This initiates the Microsoft utility that will scan and repair problems with protected system files on your computer.

Try opening Google Chrome and see whether the error message still appears.
