Windows went to sleep

[Simon771]

So yesterday I was watching movie on my PC, and in the middle of it, it sudently went to sleep.

I wasn't even near PC, and it just went to sleep by itself. I have never seen anything like that before. My power settings are at max performance and sleep mode is disabled.

 

I went to check windows logs and found something weird:

 

Error

"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."

 

And right after that error (1 sec later), there is another log information:

 

"The system is entering sleep.

Sleep Reason: Application API"

 

So because it says that something with application API, I went and check application log:

10sec before that happened there is log with this information: "The Desktop Window Manager has registered the session port."

 

Does anyone know what could be causing this?
