New computer, AMD Athlon 64 (MSI K8N Neo Platinum motherboard), Win XP Pro SP2. Computer has been running well for about a month. Recently user reports occasional blue screen crashes reporting hardware fault, suddenly his network connection has vanished.
Network connection is fine to the back of the computer. Ethernet adapter is on-board, XP reports it to be fine. TCP/IP properties are set correctly, but ipconfig comes up blank. Can ping localhost, 'network unreachable' on any attempt to ping externally.
My next step seems to be installing a PCI NIC to see if that's the issue, but I'm hoping someone here will have run into this behavior before and can suggest other possible causes for this, or other diagnostics that might help me resolve it.
