Many thanks for the replies. Am new to win 10 so do not know much about the various reliability etc apps.
PC does not turn of at same time.
No overclocking, most recent (but old as the mbo is old BIOS), all drivers up to date - with the exception of the GPU as trying to do that kept resulting in a black screen. The driver I have works and I am reticent to change right now unless this is definitely the cause of these power offs.
There are a lot of DistributedCOM errors in the event log - details such as
The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID Windows.SecurityCenter.WscDataProtection and APPID Unavailable
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.
No idea what these are, but they are through-out the log and perhaps at the time of last nights suden power off, but not todays - below.
I was playing a game called towerunite this morning and the PC suddenly turned off while I was. This is the 1st time it had done so in the day. Looking at the reliability monitor however just shows that this game stopped working, with no other info, followed by the note that windows had not shut down properly. Well yes the PC just switched off.
There is a 41 error, but nothing obvious before it. Here's the log up until the 41 error
The other errors in the system log are a few of those distributedcom erros and one from windows update about it not being able to update to 1903. Not sure on that one either as its saying pending install in update manager. And the 6008 is windows moaning it did not shut down properly
