Single Event Upsets are not to be taken seriously. You can't recreate it so that's a SEU and you note it and move on. There are folk that will freak out about events like this but we live in a world where a high energy particle could zip through and flip a memory bit at the wrong moment and blammo. SEUs are common in space, air and are reduced in caves shielded by a lot of rock.

I'd note, carry on and enjoy my PC.
