I performed a clean reinstall on my dad's five or six year old Emachines box, a few weeks later he had no internet connection. Wireless by the same modem/router good to a laptop. His LAN connection was not showing in 'network connections'. No malware found via Malwarebytes or Superantyspware. System restore did not repair the condition. Due to the very simple nature of his system I simply did a reinstall and saved his docs/preferences/favs/etc. He was back online for a month. Now he's not (about a month later). I performed an unsuccessful restore. Installed an Nvidea NIC, no go. The box is in my truck and I'll work on it tomorrow, but wth is going on? I build boxes all day long and have no issues, this is a different animal. We are running Avast free edition fwiw. Wanna kill these ads? We can help!
