I have just fitted a new CPU fan to one of my PC's, hoping to cure a repeated power-off problem.
on rebooting, all seems just fine except it is now telling me the network cable is unplugged, which it isn't! I have tried connecting a different cable (which works with my laptop) but that makes no difference. I also tried uninstalling the LAN card (Realtek RTL8139) and letting XP re-install it on a re-boot - no change.
Can anyone kindly suggest what might have happened and how I can fix it please?
Just to be absolutely clear, it's not the taskbar icon that worries me, it's the fact that the network conection isn't working and the reason given, is that the network cable isn't connected. So I cannot access my LAN.
