Question Newly build PC random restarts

[Unstable Spider]

Hi everyone!
I recently built a new PC (See signature for specs), and all seemed fine and stable at the first week.
However following the first week, I have begun experiencing random restarts on the PC without any minidump files to troubleshoot.
When the PC restarts the QLED light does turn yellow indicating a RAM issue if I am not mistaken.
This happens around daily to every second day, and occours randomly. It doesn't matter if I am gaming or just doing chill browsing and stuff-
The event log only reports unexpected shutdown, but not more than that.
I suspect that it is either a power supply issue or a RAM issue but would really like some better tests to confirm, before trying to RMA.
Any suggestions for what the problem could be?
Thank you )

Is there nothing other than Event 41 showing?
Aside from SFC/DISM, it may be worthwhile to go in and check all your connections for power and peripherals to the mobo. Make sure none of the pins are pushing out the back of the connector power supply side.

If you are running an XMP profile or any OC turn that off.

Did you perform a clean install to this build or bring over a drive from a previous system?

edit- not for nothing, and purely anecdotal but do you have any G Skill or really any other RAM you can try? I have had and have seen many issues in relation to Corsair Vengeance on AMD builds. I am not saying that is it, but worth checking.

Nothing other than event 41 showing. Already checked all screws, and power connectors as well.
Turned off XMP, and no OC however that didn't help either.
Was from a clean install.
Don't really have other RAM to try without it being a bit of a major hassle lol, but have considered perhaps to try just with one stick instead. However I just think that if RAM was the issue there should at least be some dump file, instead of just a complete random restart
