Problem with Reinstall Win XP on ASUS z70va

[Curt Ries]

I bought an ASUS z70va (Pent M 2.0 GHz) about 8 months ago and self-installed a cheap version of Win XP Pro. It ran fine for about 6 months, when we started getting warning messages that the Windows software was not genuine and was probably counterfeit, and the system started having problems and stopped connecting wirelessly. So I did a clean install of a new genuine MS OEM version on XP Pro (Version 2002 without SP2). The installation went fine, but as soon as I tried to load the drivers from the N1250 CD that came with the z70va I started getting frequent warning messages saying there were critical system and registry errors, and I was unable to dowload and install SP2 from the MS web site. The system is running but is unstable and I get constant warning messages. What do I do next? One other thing that may or may not be important - the system connected wirelessly to the internet up until recently, but the little blue indicator light for the wireless connection never worked. Please help.

I did a second clean install using the new "genuine" Windows XP CD (OEM version 2002) and the registry and system problems disappeared. I then went to the MS web site and tried to download service packs 1 & 2, but when I was asked to validate my copies of Windows I was unable to do so, and could not download SP 1 & 2. I then tried a 3rd party web site and was able to dowload SP 1 & 2, and now my system is up and running fine. I'm still worried about my copy of Windows though since it would not validate from the MS web site. Does that mean that it was probably already installed on another system before it was sold to me as new?
