Question Windows 10 randomly restarting, clues are in Event Viewer Log

[avg9956]

Hello
Recently I've been experiencing random restarts by my computer. I will carry out an anti-virus scan but in the past months I did not change any hardware components, nor did I notice any failures but I do see clues in Windows Event Viewer. I also did not change any windows settings at all for the past few months. This is the second random restart to date (1st random restart was yesterday but I thought it would come to pass). I was asleep when it happened but I did notice I went another random restart after logging into my computer. I also have Windows updates disabled as well. I am not really well verse with event viewer but I feel its my best lead as to why my PC is randomly restarting. My hunch right now is that it is a "Windows thing".

System Log in Event Viewer. Restart happened around 3:19AM when I was asleep

I also see that event id 5156 is being logged in the Security Log, literally every second. Not sure why

Application log. The restart happened around 3:18-3:19AM

Spybot maybe? Try remove that and use Malwarebytes instead.

List entire PC specs including model and age of power supply and cpu cooler.

Ok will do. My specs are all under my sig so I don't have to include it in my post. I have Malware bytes already installed as well. I usually have spybot around for its immunization feature it offers on the host file.
Age of PSU is around 3 years or so.

Actually, it just restarted again (10:25AM)! so from 3:18AM to 10:25:AM that would mean it restarts every 6 hours and 42 minutes.

What is security-SPP though. I see a related thread but I have a different event ID (1003) than his.
Event ID 6008 under System Log says that the previous shutdown at 10:26:12AM on 7/28/2024 was unexpected. This puts both spybot and security-SPP under suspicion.

I also have a program called Last Activity View. It doesn't run on the background but it can track what processes have been running. Can't find anything out of place before the 10:26AM mark unless I am missing something.

Also thought about Windows 10 end of life support. It's still in 2025. I was thinking they were sending telemetry data or something again of that sort which can cause issues.

Searching about it looks normal.

Try system file checker. Sfc /scannow in cmd ran as administrator.

I ran sfc /verifyonly instead, which checks if any files are defective and found none. I'm always adamant about the /scannow command because it fixes something but then after running that command system gets messed up so had to reformat. It happened to me back in Windows 7 days.

I turned off Spybot S&D from autoruns (program that lists everything that starts on startup). If it still persists and I see it on the event viewer log again, I will fully uninstall it with Revo Uninstaller. This would leave Security-SPP left most probably.

Also will start my PC from a cold boot, to see if the random restart still persists.
