Ethernet controller problem.


In Runtime
I'm having some problems with my current On board Ethernet controller. I just reformatted my computer, and this has decided to be the major thing to screw up. Right now, I'm using it in Backtrack 2 right now though. For some reason, it'll only work right in Backtrack, and now in Windows.

When I go to the Device Manager sector, it registers under the "Unknown Device Sector" I had a wireless card, but for some reason my computer hates those with a passion, and decides to lock up every 10 seconds, when using them. All I did to make that one work though, was install the Driver, now I'm wandering where to find the driver for an On board card, that really shouldn't need a Driver, I thought. My computer is currently a Dell Optiplex x270.

Any help would be highly appreciated thanks
