I have a dual PIII computer that runs my intranet and email. It was giving me memory dumps all the time that read issues with the NIC card. There were 2 of the same nic cards at the time, so I switched one out and put a new differant card in. Now I seem to have caused it to crash more times. Basically it will hang once a day. No memory dump, no nothing, just fail and hang. The event log says nothing, and the there is no sign of any virus or anything? What could it be? Do I need to have the same NIC cards in a multihomed computer, or can I have the setup with differant cards?
