To be brutally honest, IF the solar flares hit that hard, then I'd imagine there'd be a lot more worrisome issues to deal with.
A personal computer, yeah, thats a pity... However, just speculating over the amounts of electronic equipment that can be disruptet/shorted out by this, leads me to believe that a personal computer is the least worrisome thing on my mind.
That said, it is possible to take precautions
(And for the record, no, I don't believe anything will be affected by it on a noticeable scale.)
