Windows 7 Ultimate x64 new installation with no devices found?

I completely formatted my computer to Windows 7 Ultimate 64 bit from Windows 7 Home Edition x64, I put in the correct product key and then when I attempted to connect to the internet I couldn't because I don't have the correct drivers.
Back when I used to use Windows XP I put a little CD in and then installed the drivers from Device Manager but now with Windows 7, I put the CD in and I can't install the drivers. They show up with a tiny symbol with a yellow exclamation mark on it (it was like this too back when I used XP, but I had no problems then,). Does anyone know what I can do?
The uninstalled drivers are these:
Base System Device
Base System Device
Ethernet Controller
Network Controller
SM Bus Controller

Also, if this helps my laptop is an Acer Laptop.

Windows 7 Home Premium
AMD A-Series Quad-Core Processor A6-3400M - 4MB cache, 1.4GHz
15.6" HD 1366 x 768 pixel resolution - 6GB DDR3 SDRAM
500GB hard drive
integrated Super-Multi drive
5-in-1 card reader
AMD Radeon HD 6520G Graphics
802.11b/g/n WLAN
Gigabit LAN

I'm stumped here, any help would be greatly appreciated. When I right click and click "Update Drivers" it says there are no updates.

Have you tried using Device Manager to manually install the drivers? If you right click on the device in Device Manager and then click on "update drivers" you should see two options. The first option will search automatically for the driver, but the second option will allow you to browse your computer for the driver software. If you have the driver cd inserted you can then "Do a search for the driver in this location" and navigate to your cd drive. If the right driver is located on the cd, Windows should then "find" and install it for you.
