My network adaptor has disappeared after Win 7 32 bit install

Hi,

I was running Vista before.

I've installed Win7 on a formatted drive and my internet connection is gone.

The Network adaptor along with -

PCI Simple Comm Cont
Sm Bus Cont
Univ Serial Bus (USB) Cont

Have all yellow warning symbols.

I cant run a utility as they seem to need a network connection.

I've searched for a LAn driver for my Gigabyte H67N-USB3-B3 motherboard.

I've tried unpluggin it from the mains overnight.

I've tried changing the power saving settings.

Can anyone help please?

Thanks

Thanks so much for a quick response.

You are correct, I can't see the LAn connection in device manager.

I think I just enabled the WOL in bios. I enabled something called erp support.

I'm going to try your links and install that.

Which chipset do I install? Is it-

Intel Management Engine Interface

&

Realtek LAN Driver

Thanks

I installed -

Intel INF installation

&

Realtek LAN Driver

I had installed that driver before. It now shows as a network adapter in device manager, but when I go to create a connection it states it cannot find hardware.

I still have these with yellow warnings-

PCI Simple Comm Cont
&
Univ Serial Bus (USB) Cont

The Sm Bus Cont is not showing with a yellow flag.

I checked the Realtek and it shows as "no clonflicts".

In details tab for PCI Simple Comm Cont it states-

Property and then a drop down with Device description

Value and in the window below PCI Simple Communication Controller

&

In details tab for Univ Serial Bus (USB) Cont it just states-

Property and then a drop down with Device description

Value and in the window below Universal Serial Bus (USB) Controller

Nothing else.
