My network adapter on my dell is not found


Jun 26, 2012
My computer started shutting off and not turning on. I had installed new parts a while ago and so I switched the new parts with the old ones (power supply and Graphics card) and it worked again. But i couldnt connect to the internet and i did a diagnoses and it said adapter not found or correctly installed or something like that. I couldnt find the adapter either. I was going to download the network adapter driver from the dell website on to a thumb drive and install in onto my desktop but i do not know which one to download. Or if this is the right solution.
