Ok I know some decent amount of hardware troubleshooting but this one is

One of my kids has a PII 400 system with 2000 on it and it had a virus and spyware on it. So I wiped out the HD after upgrading the mobo to a better one and more memory and PIII 600 cpu. Now when I tried to install 2000 I get the blue screen of death saying something about disabling Caching and Shadowing.

The HD was low level formatted, all periphals disconnected except for CDROM, floppy, video, just the necessities. these are all the same periphals that were in the original installation. I even tried recreating the 4 install floppies. I even have now switched the mobo back so its only the RAM and CPU that are different now. Still BSOD.

Any suggestions?
