New Build Shutting Down Overnight, Every Night

[locheim]

I recently built a new PC, which worked fine until recently. For the past few days it is shutting down overnight, every night. In the morning, I have a hell of a time getting it to come back on. This morning I removed the CMOS battery for a few seconds, and it booted after replacing that.

This is roughly my build:

Running Windows 10.

The only issue I can find is this in event viewer (presumably near the time it shut down):

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{D63B10C5-BB46-4990-A94F-E40B9D520160}
and APPID
{9CA88EE3-ACB7-47C8-AFC4-AB702511C276}
to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

Any ideas why this PC runs just fine when I'm using it but seems to shut down overnight?

Just asking the dumb question - you have power settings set to stay awake and not sleep or hibernate?

Unfortunately I don't have a solution for you but you should send me some benchmarks w/ the 6100 / 950 once you solve the problem. I've been curious about that combo for a while.

Yeah, not hibernating or sleeping, this thing is fully shut down. Hitting the power button did nothing. On previous attempts, I'd unplugged it for a while and swapped power cords (so I thought it was maybe a bad power cord) but the problem is still occurring. This morning, after removing/replacing the CMOS battery it booted up without issue. Is has never shut down while in use (~3 months).

I'll try playing with power settings though, maybe some combo of Windows 10 and the hardware is doing something weird.

One thing that isn't apparent from my parts list is that I'm booting to a 120GB SSD with data on a 1TB HDD.

@Casey Jones, sure thing, how do you want those benchmarks? Feel free to PM.
