Dear Group, An ASUS motherboard failed in a Win XP Pro pc belonging to a friend of mine, so I have replace it for her. Asus no longer make this mobo, it's not available so I bought a board from ASrock with the same socket, however the ASUS board had NVidia chipset while the ASRock uses AMD chipset. It's socket 939 and these are hard to come by now. Windows XP repair installation has been completed, it starts normally and offers logon to the pc or the domain controller. I select the pc and after a couple of seconds a Windows Product Activation message appears: "This copy of Windows must be activated with Microsoft before you can continue. You cannot log on until you activate Windows. Because activation cannot occur in safe mode, please restart your computer in normal mode to activate Windows." And the same is true when starting Win XP Pro normally. The message for normal boot and logon is: "This copy of Windows must be activated with Microsoft before you can log on. Do you want to activate Windows now? [ Yes / No ] " I select Yes and no other window or message appears. It is connected with a LAN cable to my router, to the internet. So web activation should work. I have left it like this for over an hour, but the screen just stays with the Windows background and nothing else loaded on screen. *** Router Info *** Router is not seeing the Win XP Pro pc as an Attached Device. So I assume Network functionality is not working. This could be why it's waiting for activation but not completing. The light on the router is lit up, but logging on to the router I can only see my own pc and not the Win XP Pro pc. If I select No on the activation message I get sent back to the logon screen. I am not selecting the Domain Controller because I am not located there, it's a few miles away. I could go there but I think it would be a waste of time, is it worth actually trying this, would it make any difference since my own router has internet for activation? It's a genuine copy of Windows etc. What can I do? My thought is to take the hard drive out, put it into another pc and rename the WPA files, then put it back into this pc. My hope is that any problems with them may be solved this way, new files would be completed etc. But I am still left with what appears to be a Network Driver problem. I really am stuck with this one. Thanks in advance.
