Are you ever found an error message : "Whoa! Google Chrome has crashed." ?

Issue
This error displays when Google Chrome unexpectedly shuts down.

Solutions
Try restarting the browser.

Whenever possible, Google Chrome will restore webpages from your previous browsing session.

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.
Check for conflicting software.

You can check for conflicting software on Windows by typing about:conflicts in the address bar. If you have software that is known to cause Google Chrome to crash, it will be highlighted for you on this page, along with any recommended actions to resolve the conflict. In many cases, the conflicting software is malware that needs to be removed using anti-virus software.
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:
Enter the keyboard shortcut Windows key +E to open Windows Explorer.
In the Windows Explorer window that appears enter the following in the address bar:

Windows
Windows XP: %USERPROFILE%\Local Settings\Application Data\Google\Chrome\User Data\
Windows Vista/ Windows 7/ Windows 8: %LOCALAPPDATA%\Google\Chrome\User Data\

Mac OS X: ~/Library/Application Support/Google/Chrome/Default

Linux: ~/.config/google-chrome/Default
Click OK.
In the window that opens, rename the "Default" folder as "Backup."
Move the "Backup" folder from the "User Data" folder up one level to the "Chrome" folder.

If you continue to see the error, try creating a new user profile to replace your current one.
