    It depends on your definition of "frequent" .

    You really need to get a good UPS if that's the case.

    The one thing to keep in mind is the flow of power to your house isn't 100% constant. It can fluctuate to a small degree. A good power supply can help correct this but a good power supply isn't foolproof. A UPS will also help filter the power.

    Blackouts will put a strain on the Hard Drive. Whenever I've seen a Blackout, the power fluctuates beforehand and the drop in voltage (undervoltage) can damage hardware.

    Yes, if the PC shuts down unexpectedly then this can corrupt the O.S.. Sudden shutdowns are also hard on mechanical hard drives.

    Power outage or black out likely won't cause damage to any hardware, but it can cause issue with your OS if the system isn't shutdown correctly. What normally follows power outages are power surges. This can damage anything plugged into an outlet. If you are having frequent power outages, you may want to look into whole house surge protector and make sure you have a quality surge protector for your computer equipment (tower, monitor, router/modem, etc..).

    A UPS or Uninterruptible Power Supply will supply power for a short time during an outage and can prevent your PC for shutting down unexpectedly.

    power surge can fry the internals. you need, at minimum, a surge suppressor. an uninterruptible power supply is better

    Old hard disk platters may crash, circuits can fry, and motherboards will die for no apparent reason at all.

    Unless you have it on and are working when they have a power loss it shouldn't hurt it at all. Once in a while if that happens while you are doing something you may lose your work and also it has corrupted a file or so on mine when it happened but that isn't an every time thing. If you have a lot of them it would be wise to invest in a battery back up unit and that will give you from 5 to 15 minutes to shut everything down depending on which one you have.
