I ran into the issue with the same device driver CRCCHK.SYS on boot.
I couldn't get around it and VISTA was acting erratic so I reinstalled after
a fresh format.
After a reinstall, installing the nVidia forceware drivers (beta for Vista
X64) for the SATA fresh from the install, it was doing the same thing from
the get-go.
I can't boot normally. Only safe mode. Are there any specific log files
you'd like to see? I'm on my other machine right now but could login safe
mode w/ networking and see what I can do.
