New build. WD Hard drive. XP Home operating system. Enter key to register product (WindowsI mean) and says it's invalid. Called Microsoft who says my key is correct, but gives me a new one anyway. Still says it's invalid. Microsoft says it's a hardware reading issue. That makes no sense at all to me, but what do I know? Does this make sense to anyone else? If so it HAS to be hard drive related, no?
Not sure what that means. It's an OLD SP 1 version of windows, and seperatly I have an SP 2 Update disk. But microsoft is confirming the key, and then giving me a new key. I've used the CD with the key on an earlier build as well. Am I misunderstanding?
Not sure if this applies here but, a few years back I noticed when overclocking that if my cpu was very unstable I could sometime get to the xp loging screen but xp reported my password as wrong every time and would crash shortly there after.
It's an extreme example but it shows that something like this is possible when there is an unstable component in your system.
Still, I think it's more probable that this is an issue with the version of your OS, emphasis on probable.
Double check your bios configuration, you never know what could go wrong with a new build.
Hmmm just use Linux kidding thats a weird issue, I would try reinstalling and running some sort of bootable ram test CD (there are too many to download online just pick one, I recommend Memtest86)
Maybe run the ram test first then do the reinstall if your ram comes up clean
Edit: and if after all that your computer still will not load XP, try loading up a version of Linux (just for testing purposes) if that works then maybe its your Windows disk ? a scratch at just the right bit....
