Question: how can i make the computer forget everything iv ever googled or searched for? 

Answer: If you have history on your hard drive that you don't want anyone to ever know was on there then replace the drive and load it with fresh software. Take the old hard drive and pitch it into a roaring fire. Even formatting won't do you any good. Formatting does not erase. It only hides stuff which can be retrieved with the right tools and know how.
