First try "add new hardware" and see if it finds the card.
Then check to make sure it is turned on in the bios.
Could be your motherboard drivers have been corrupted. Being an onboard item it is dependant on these drivers. So try reinstalling them - but while you are at it download the latest bios and motherboard drivers.
SOMEONE HELP PLEASE.
I am totally lost. My network card is totally lost. i am running windows 2000, and in my device manager there is absolutly no network card showing. My biggest problem is its an onboard network card. The motherboard is a MSI km4m with an AMD chip in it. none of the drivers i seem to find do anything, especially considering there is no network card showing to add the drivers to. Does this mean the network card is totally dead, because it was working, and then i made a few changes to the users on the system. If anyone could tell me where i am going wrong it would be apreciated.
