My PC just shut off by itself all of a sudden. I thought there was a power outage at first, but it wasn't. It really did seem like it, though, unlike the other random shutdowns before. And the last time it had a shutdown was nearly 6 months ago, last year. Had to turn it back on myself. WhoCrashed showed no report. No sign of overheating, either. Was just using Photoshop and listening to Youtube.
