I disconnected my WiFi from the taskbar (I do this sometimes when I’m AFK for a bit… call me paranoid) and turned off my monitor but I left the PC on the desktop not doing anything (although that’s subjective, it’s doing plenty in the background). Half an hour later I return to my PC and it’s off.
In Event Viewer at 19:23 it logs there was unexpected shutdown at 18:40 (while I was away). At 18:27 there was a DistributedCOM event, a yellow warning triangle. Specific text reads: The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID.
I’m not entirely sure what that is without Googling it, which I haven’t done yet (and probably won’t). At 18:38 it records a Kernel-General event, nothing untoward here. The next event is at 19:22 another Kernel-General, this is after the logged shutdown.
Is there somewhere else I can look to work out what caused the shutdown? You’d think just powerless but I can see no obvious reason for this, there was no general power outage to the room or the house as a whole. Dodgy PSU perhaps? Maybe, but it hasn’t giving any clues that it’s faulty so far. Well, at least until today.
As for connected USB devices and other I/O there’s a Rift CV1 and Valve Index but they’re both disconnected from the leads. Though Rift sensors are plugged in. A Wooting Two keyboard and a Logitech mouse, speakers (off) and an external SSD docking station (also off).
I can’t say I’ve ever had the PC randomly shutdown before (in it’s current hardware configuration at least) while actually using it. So the fact that it did this while I was away from it is troubling.
Oh and no one else in the house and cat not around (or even capable of shutting down a PC).
Or a ghost turned it off.
