well there are several things why your google chrome does not work. here are some tips:
check if you have another browser other than google such as internet explorer, netscape, firefox , determine if you have internet access
If it has, then uninstall/ reinstall your google chrome..
If it does not then check your physical connections on your pc
check the lights on the modem / router if it is all lit, if it doesnot , contact your modem/router provider. If it works, then proceed to next step:
Then type the "ipconfig" command on the command prompt by clicking start > all programs > accessories > then click command prompt
if the IP address starts with 0.0.0.0 or 169.xx.xx.xx consult your Internet service provider, if it is 192.xx.xx.xx then proceed to next step:
Type the ip address 192.xx.xx.xx on the internet browser, if it replied , then configure your router settings to make sure that the other ip addresses would work on the internet browser. Then type www.google.com
