Solar flares happen, but they don’t do anything more than make radio reception wonky. That means that GPS, radio, satellite TV, and other such things will have degraded/no signal (my GPS intermittently shows me about 100 miles North of my actual location) but aside from that, there is no effect. Home computers will be fine, and no other electronics will be harmed either.
The general rule of thumb is that any solar flare powerful enough to permanently damage consumer electronics will either kill you or give you super-powers. I have seen many solar flares, and I am neither dead nor ready to join the Fantastic 4, Thunderstorms cause far more damage.
