Does your stack auto-save anything at any time? If power fails during a save operation, there will be another stack file of the same name preceded by a tilde (~). Deleting the tilde will restore the prior version of the stack file.
Sometimes a power outage can damage the partition of the HDD. I would have UPS backups on all the systems you deem critical, and check these UPS systems every three months or replace them outright every three years (typical life expectancy of a lead acid battery).

But when it failed (4 or 5 times a year) usually the same customer (same hardware same windows 7 )I had to log in and copy a blank livecode stack. In the end I had to save the info in the Sqlite database - No problems since. The stackfile never seemed to damage because of a power failure/outage or anything - but had a greater chance if that was the case. The funny thing was if you did switch the power off off without doing a proper shutdown there was no damage 99.9% of the time. Never did get to the bottom of it.
