My area has many "pop offs" where the power goes suddenly off due to a short to ground somewhere in the local area grid, and then comes right back on (usually). Causes my computer to restart, sometimes not successfully, but I lose everything I was doing. When it's unsuccessfull I have to flip off the main PSU switch then back on and press power button. I think i have a surge arrestor inline. Do these sudden offs (pop offs) hurt my computer?
