    Depends how tolerant your PSU is to voltage fluctuation. I'm sure if voltage is too low it will trip.

    Does it still power on? Boot up fine? Not harmed. PC's are digital. Power is converted from AC to DC. It either provides proper power or not. It will shut down if not.

    Unless others are in the same area as you are no one can say why. Does your system have Power Surge unit that your computer plugs into? And laptops have their own battery so should the power flicker or cut out it will not show on the computer like you think it would for a Desktop requiring power from a outlet source. But I seen where my house would flicker sometimes but the computer is fine but it is hooked up to the power surge strip so it filters such flicker volts without the computer seeing it.

    It's not just computers that will do that, Lights seem to be the first (and usually only) thing affected by minor fluctuations. Why this is I don't know but I can recall lights flashing and my microwave not being interrupted at all.

    Conventional light bulbs light output (lumens) is directly related to the voltage applied, so you will notice it visually. Computer power supplies are designed to run with a range of voltages like 80-130V. There are capacitors that will maintain the steady output voltage that the system needs, as well as provide constant power for a short period even if the power "flickers". If the voltage gets too low, it will just cease to work and switch off on its own.
