I have recently reinstalled windows 7 on my DELL inspiron n5010 laptop. Do i need to install all the drivers listed on this page
No you don't need install all the drivers and principally programs that already comes with a CD in new Laptops or Computers.
I would suggest to install all the drivers that appears as Driver Not Found in the
Device Manager. When you have all the drivers in
Device Manager installed, let Windows update them.
