Which version of ubuntu is installed in the second hard drive. WHat happens when you try to open chrome. ANy error messages?
I am an expert here and have no control over billing. However i know for a fact that you don;t have to pay unless your problem is solved
Now as far as your problem is concerned, i am guessing that a corrupt addon or plugin is causing this. To fix that:
1. You can try uninstalling and reinstalling chrome.
2.You can force Google Chrome to regenerate all configuration and profile files. You should be able to do this with a single command from terminal:
Keep in mind that this will delete all of your bookmarks and settings. So hopefully you have them synced with your Google account or backup somehow.
Keep me posted.
