    The most danger lies in if the system is writing to the hard drive at the time. You can corrupt or damage hard drive blocks.

    if the power is to go off, you have a slim chance of damaging the Hard drive (if it is in the middle of a write) but nothing else will be damaged.

    on the other-hand, if there is a power surge, then hardware can get damaged

    Mainly as bwilmot has already pointed out, you run the risk (pot luck really) of preventing a system file being written (returned) to the hard drive as it would be if you shut down in the proper way.

    By the law of averages, eventually (maybe even on the first attempt) you'll try to BOOT and it will fail, due to the file that didn't get written on the previous sudden denial of power.

    Hard drives use the speed of the disk to create an air cushion between the disk and the head. On older drives sudden loss of power could result in a head crash due to the head not retracting before the cushion dissipated as the disk slowed down.

    I believe newer hard drives are designed to have the head retract quickly enough on power loss that this won't happen.

    The purpose of an orderly shutdown before power off is to ensure data in memory has been written to disk where neccessary.

    Modern PCs store data in memory caches before writing to disk to improve speed, so you could get corrupted files even if the disk doesn't seem to be doing something at the time - eg the first half of the file may have been updated and not match the second half which hasn't been updated because the data was still in memory at shutdown.

    Damage to system files may make it look like other hardware is damaged, but suddenly turning off the PC won't have actually damaged the motherboard, ram, etc.

    Any damage should be fixable by restoring damaged files, or at worst by replacing the disk drive (and restoring files).
