@gemlog I did a quick check (although not the full 8 gig of RAM), although I suspect more that I left lots of random tabs open on 2 browsers when I went to the shop as well as Dropbox trying to pull 100 gigs of various files down the network at the same time..
Now I have reconfigured the Dropbox client for a more limited set of directories and have Anydesk running I've left the PC switched on and connected to the network so I can keep an eye on it remotely to see if it behaves..
