Windows 10: PC seemingly randomly restarts itself when idle

As explained in the title, my computer seems to randomly restart on its own, while idle, as weird as it is. I've checked my CPU and GPU temps, and they are normal Averaging around 40°C on my CPU and 50°C on my GPU. I've scanned for viruses, no detections Malwarebytes. My build is around 3-4 years old, so I doubt it's my PSU. My event log says they were It's happened twice now unexpected shutdowns. Any help for my problem?

One of the PCs on my Home Network disappears seemingly randomly

I've been lurking on this forum for a couple of years, often finding the answers, or solutions to my questions, however never found it necessary to post a request for help, but here goes: One of the PCs on my Home Network disappears seemingly randomly. My network consists of 2 desktops (W10 Home W11Pro), and 3 W10 Home Laptops. All the W10 versions are 22H2 The W10 desktop disappears off the network randomly? It can be readily restored to the network with Network Reset though. I see that one of the responses to this type of question is make sure SMB1 is disabled and it is. So if any help in the steps to narrow down the problem it is appreciated.

 

PC Randomly Restarting after installing new Ram!

Tried your suggestions, but still had a restart! Also ran memtest overnight (13 hours according to memtest) and had no errors! Also ran Passmark Burn in test for a couple hours testing everything and had no errors or restart. Could fitting the new ram have triggered something to go bad like my mobo or psu?
