I think you need to put down the coffee and relax a little. Google doesn't have your computer, but the do see what you do online. Rebooting won't help.
You can turn off google search tracking you in your settings when you log in.
You can use an anonymous proxy. Of course then the people that run the proxy can track you even more.
Your best bet is to just stop using the Internet.
