Based on past experience I realize that Windows 2000 loaded on a drive mounted in a PC from one vendor won't work well, if at all, when dropped into a different PC from another vendor. If the same vendor is maintained but the CPUs are different will similar problems arise? A 40GB drive works perfectly well but the Micron Millennia AMD PC is lives in has a problematic mobo (I suspect there's a short somewhere) and I can get another Millennia but with a PIII "inside". When the AMD/Micron gets plugged into power the fans sputter on and off at short intervals but the NIC doesn't go green and the power button won't activate the PC.

The CPU makes no difference to your HD, it should work fine. If the board is slightly different you may need to load a few drivers on start up. I regularly swap drives fron one PC to a completely different one without any problems other than loading drivers! Wizard ICT. Microsoft Certified Professional

Thanks wizard, the feedback is appreciated. The original swap I mentioned which didn't work was taking a drive built in a Dell GX series and testingb it in a Compaq Deskpro. The OS booted to repeated blue screens so I figured the same would happen regardless of which vendors cases I was using. As it turns out the power supply was the root cause and was my second suspect item. I figured it was more likely to be a mobo going bad before a pwr supply but not this time.
