Install the Media Direct, if you have it, then the operating system disk. Then make sure you have these drivers on a disk before you install the system. It should go pretty smooth.
The Desktop/Notebook Utility needs to be installed first(if applicable), then the chipset drivers. If they are NOT installed first, then the rest of the drivers will fail to install.
Since the operating system was re-installed did you remember to go to drivers and downloads, enter your service tag(DO NOT POST SERVICE TAG here or your post will get deleted, since it contains your personal information), and install these drivers in this order.
Hint When downloading the drivers, make a folder for each drivers and name it with the device it belongs with to make it easier to install them in the proper order.
Desktop System Software or Notebook System Software(if applicable)
Chipset or SMBus driver
Processor Driver (if applicable)
Input Drivers (keyboard/mouse)

First make sure your machine has a 64 bit processor. I'm guessing you already know that, otherwise you wouldn't be asking the question. I used the processor ID utility from Intel to make sure, then downloaded the Windows 7 upgrade advisor. I'm in the middle of doing this on my wife's laptop as I write this. If you have the media, I recommend you see this site for ideas and additional guidance - http://www.winsupersite.com/win7/
