ok well i got my new HD Western digital 80gig, i installed it and installed the OS. installed everything else and it still restarted. i restored backward to just after i partioned the drive and installed vue. left it rendering for awhile. it rendered for an hour and a half, completing preview render. started a final render at a smaller res. i stopped that and started a 640 final render and went to bed... woke up and it had restarted... sigh...
