HI everyone, new to the forum.
Bit of background: I am a Windows convert, having got fed up with the AI slop and ads being forced on me. I was an advanced windows user, being comfortable with the Terminal/Powershell, and with the registry, so I am not a newbie with PCs. However, I am fairly new to Linux. I am still comfortable using the Terminal, but currently I don't have a full grasp on all the commands/syntax.
With that out of the way, I am having a big issue with my ZorinOS 18 Pro installation. When I am using it, it runs perfectly, very smooth and stable. But when I leave the PC, at seemingly random times, it just reboots, so when I come back to it, it needs to log in from a cold start. Sometimes I can leave the PC for hours and its still fine when I come back, other times it's only half an hour later and it has rebooted. I have installed the 'Logs' app but I can't really understand it all. I have turned off sleep and am running it in performance mode.
One other issue that may be related: The Wifi on my motherboard isn't working. If I run 'lspci', it comes up as "Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)" but no drivers are installed and I am having trouble getting that working. It's not really an issue, as I use Ethernet anyway, but it may be important.
My hardware: Ryzen 7 5800X3D CPU, 32Gb 3600MT/s DDR4, Gigabyte X570S Aorus Pro AX motherboard, AMD RX 6700XT GPU.
