Vista Enterprise won't boot after crcdisk.sys

[Guest]

I have a Vista Enterprise PC that has been running well for a couple of
weeks. It was a fresh install onto 120gb SATA drive which was formatted
durint the installation process. Everything fine until a couple of days ago
when the PC bluescreened. No new hardware or software was added immediately
prior to this event. The PC booted successfully after that, but tonight it
has just bluescreened again (unfortunately I didn't make a note of the
error), and now it will not boot. It starts the boot process then the screen
goes black and restarts. If I try to start in safe mode it loads crcdisk.sys
the restarts. Last known good config does not work. Any ideas on where to
start with this one?

Update - I left the PC turned off for a couple of hours and it has now
booted. On booting it ran a chkdsk on drive d: (second physical hard drive)
and found faults in the MFT. I have hundreds of Event ID 57 volsnap "The
system failed to flush data to the transaction log. Corruption may occur." in
the system log. Not sure if this is the source of the problem, although I
can't now remember if I reformatted this second drive prior to installing
Vista. I did enable snapshot on this drive a few days ago, so it seems like
a possible culprit. I have disabled the snapshot service on this drive and
disabled write caching on both drives and will monitor over the next day or
two.
