It seems you're not yet aware that Win7 is the first driver-complete OS, with almost all drivers provided by the installer and then quickly updated via optional Windows Updates when you enable Automatically deliver drivers via Windows Update (Step 3).
Please read Clean Reinstall - Factory OEM Windows 7 which steps are the same for retail. It explains all of this.
This is not XP. In WIndows 8 you have no interaction with drivers at all which are all done in the background, an improvement which was developed in Windows 7.
As advised if you're uncomfortable with the Clean Reinstall then try the Repair Install which easier.
