Some manufacturers are weird some give you a CD (or ISO for one) to load the utilities for flashing the bios then want you to have the bios file on a floppy. Some have methods to do this with a usb drive or straight from a floppy. Best instructions are probably on their site somewhere.

I don't remember the exact name of it but there is an event viewer / error reporter tool in vista that can give you some more info on blue screens.

I'd consider replacing any "old" hardware that they're not sure is 64-bit compatible.
