The value of power cycling is to determine how intermittent the problem is. If the problem only ever occurs once and power cycling fixes it then that is effectively a permanent fix. If it comes back next year and power cycling fixes it again, you know there's something wrong but it probably won't be an actual problem for any practical purposes unless it gets worse. If you find yourself to need to power cycle every month or every week or even worse, increasingly more often, chances are you're going realize that the root cause must be investigated and fixed in a matter or months or weeks or even days.
