I am running windows xp with an onboard nforce nic. My computer started to freeze about a minute or so after logging in. Disabling the nforce networking control hardware device (NIC) solved the freezing problem, but adding any NIC (USB, PCI) causes the the computer to freeze. I t is a fairly old computer so I will need time to get specs, but if this sounds familiar let me know how the problem was resolved.
