[SOLVED] Unexpected Restarts & shutdowns

[ChristianO]

I've been searching online, alongside my event viewer, to find the cause of the issue. My PC will unexpectedly shutdown or restart - sometimes under load and other times it will be idle. I started having this issue while playing The Outer Worlds, but I know it isn't a system issue, no overheating, PSU problems, etc.

I've looked at the event viewer(filtering 1074, 6006, 6008) and all I am getting is:

The process C:\WINDOWS\system32\MusNotificationUx.exe (CHRIS) has initiated the restart of computer CHRIS on behalf of user Chris\Chris for the following reason: Operating System: Service pack (Planned)

The previous system shutdown at 11:27:47 AM on ‎11/‎5/‎2019 was unexpected.


I get a few of these info logs in the event viewer and they're always followed by the error above - "unexpected shutdown".
Any solutions or any idea what could cause this?

There is no pre-cursor to the errors, I can't predict the issues, it has been completely random. I've had 1 restart today, 2 yesterday, and then almost a week in-between.

hey Chris,
My canned random reboot Rant
Random reboots are usually caused by the PSU, the RAM or software AND in that order of likely-hood.
PSU - If you can borrow/swap a PSU for testing. sibling/friend you can swap out the PSU and each system will be testing the other.
RAM - run the system with one stick of RAM see if stability returns if not Test all the RAM with memtest 86 for five passes or overnight. if you get no 0 errors after more than five passes the ram is good. with the random reboots I would suggest running this test after the PSU swap or after the PSU has been cleared.
Software - Drivers or other issues can cause reboots. Boot to a linux distro on a USB drive. mint linux will boot to memtest86. you can run the OS from the USB and await reboot.
end canned rant

I'll have to give it a go - it could be very likely, I've just never experienced random restarts like this as I try to keep my PC up-to-date. I appreciate the response!
