What Drivers do I need to install for my laptop?  

Hi I'm Julius, 14 years old, and I just got my laptop reformatted and I have no Drivers installed yet, I don't know what are the right ones to install. I tried Dell Driver Installer, Intel Network Driver, Complete Internet Connection Repair Tool, Intel Driver Update Utility, etc. but none of them solved my problem. I've turned on Simple Network Management Protocol (SNMP) already for the Intel Driver Installer but this is what it said "No Intel(R) Adapters are present in this Computer". I have a file here called DxDiag also troubleshooted my laptop and here's what it said:

Ethernet Controller doesn't have a driver
Network Controller doesn't have a driver
SM Bus Controller doesn't have a driver
PCI Simple Communications Controller doesn't have a driver
Hardware Changes are not Detected

Here's some few informations and specs of my laptop just incase:

Laptop: Dell Inspiron N4050
OS: Windows 7 Ultimate x32
Processor: Intel(R) Core(TM) i3-2350M CU @ 2.30GHz 2.30GHz
Installed Memory (RAM): 2.00 GB
System Type: 32-bit Operating System

Okay thanks

I found another problem, the 2 files I downloaded won't open whenever I transfer it from the pc to the laptop

Is it the laptop that has the problem or the usb?

Just wanna tell to some pips that have the same problem, just go to your Manufacturer's website and find the drivers you need but install your Chipset driver first. Like mine on Dell, after installing the Chipset Driver.. I find the 3 left drivers that are needed for my laptop. I searched there Dell Adapter Driver, then after installing it I've connected to my router using the cord and downloaded the other drivers using troubleshoot.
