Windows 7 not responding

[-CJ-]

hey wassup guys, I freshly install windows 7 on my laptop. I did the complete installation (format everything). Since i got 7, I got a lot of "Not responding" alert. Every app can goes "not responding" randomly and freeze for about 30-60sec. I updated all the drivers, did all the windows update. I don't know what to do now, How can I know what is causing that problem ?



PS : Sorry for my english. It must be difficult for you to understand everything
