How do I get google chrome to work?

Ok so at the moment I am using firefox but since it doesn't let me copy and paste images of the internet (only lets me when I save the image but its quicker to copy and paste). I've been wanting to use google chrome. So the download works fine. And when I start up google chrome it says I have to sign in which is fine but everytime I try and sign in with my google account nothing works it just keeps saying there is no connection but there is connection. I've tried uninstalling and installing it again and it just ends up the same way each time I try. I have windows 7 if that's information you need to answer my question.
Taylor- I tried that, it doesn't work either.
