Is it safe to use a computer during a storm that might involve lightning discharges? I'm talking about normal every day usage like browsing the web and gaming, not stuff like installing OS or BIOS updates. I'm mainly worried about permanent damage to my computer hardware, but if there are any additional risks involved, those can be relevant as well.
In case it matters, my computer is plugged into a surge protector (this one) and I live in a normal Belgian residential house with 1 upper floor and an attic.
