Really can't give advice on Chrome since I don't use it. One thing you need to do is update your Java program.
Go here to download the latest version:
http://java.com/en/download/manual.jsp
Choose the Offline install and save it to the desktop.
After you have downloaded then close all your browsers, email programs etc. and go to Add/Remove and Uninstall ALL Java that you see there
Java Auto Updater
Java(TM) 6 Update 24
Once you have uninstalled those then double click the install file on your desktop to install the new version. WATCH the install VERY CAREFULLY because it might contain a toolbar or other item you don't want. If you see one of these "extras" that the check mark OUT of the boxes you will see there so you won't get the extra item offered, like an Asktool bar or Yahoo toolbar, something like that...you don't need them
Allow the install to coninue to completion. Once it finished then open the browser and go back to the download page and on the right side look for Verify Now, click that to go to the verification page to be sure the install went as it was supposed to.
Then try your Chrome and see if it works ok.
