It's not a virus.
before I decided to reinstall I was able to boot into safe mode with networking under windows 2003, it was just right before the Ctrl-Alt-Del in normal mode that it would blue screen.
When I tried reinstalling last night, a new installation on a fresh partition, I got into the graphical part of the installation, but before any of the 'choose your options' stuff came up is where it blue screened, probably while detecting the hardware/bios.
I've read elsewhere about pressing F7 when the text mode of the installation is showing the "Press F6 for scsi controllers" part, but I have not seen it hit that part of the install.
