Help needed please. Sony Vaio laptop with missing drivers

Hi. New to this forum. Been having a nightmare recently. After re-installing (or rather Microsoft operative re-installing) W7 as a repair installation, I find I can't get onto the internet via my usual Tentel wifi connection. The router is fine, the problem is the network hardware on the laptop and drivers (or lack of). Re-installing has removed the Sony drivers. Some of the laptop works OK (as far as I can tell), but I can't get online, games don't operate properly (Video card issue), and Microsoft tech dept. operatives are worse than useless. One called Racquel even said she wanted to charge me for helping, even though a Microsoft operative caused the problem! I need to know whether there is a tried and tested method for problem finding in the Devices section of the laptop, and exactly which devices and drivers I need. Looking at Sony's website for drivers for my particular Vaio (VPCCB3P1E), it is not at all clear exactly which drivers I need. Anyone have any experience here? Many thanks.

Don't feel bad... That is a common problem when loading a fresh OS.
Go to the website of SONY esupport and select Drivers/Software for your model and ensure you select your specific OS version for each driver you download.
There is a specific order you need to load the drivers otherwise certain functions will not work properly.
This will resolve your problems.

(seriously, this link was the first hit on google search for that model)

If wired connection to your router works, then you can download those drivers directly to your computer.

As usual, there is listed multiple drivers for one part like the graphics card or wlan. I don't know what's in your computer so there is two ways to do this.
Either look in the device manager what drivers are missing, in the details tab there is a string that you can type into google and the result usually tells you one way or another what the component is. Then you can download the correct driver in the above page.
Other option is just to download drivers and install them until nothing is missing. Usually trying to install a wrong driver doesn't do anything, it's just wasted time and bandwidth. For graphics card there is multiple options, I'd take the latest one first.
