Possibly its the power supply unit, i would check that first, the event you copied basically just states that all the components lost power abruptly.

any blue screens?

Nope. No blue screens.Thanks for the suggestion!...I'll check my PSU then.

Could be motherboard issue as well. Mobo & psu are connected on I guess pin 16 on ATX connector. Run live Linux for a few days and check if the issue repeats with another OS
