Google chrome home page missing.?

[Tuhin]

Hey why don't you reset Google chrome
Google Chrome creates a folder User Data to store personalize settings including preferences, history, download list etc.
To Reset them, just delete all the files and folders from User Data and the locations are:

For Windows XP
C:\Documents and Settings\UserName\Local Settings\Application Data\Google\Chrome\Application
For Windows Vista or later
C:\Users\UserName\AppData\Local\Google\Chrome\Application

hope that helps.
