For some reason my computer seems to be very unstable. I have hunch that it might be because of my graphics card (5500 XT) or Gnome. I'm experiencing the same problem after switching from Ubuntu to Manjaro Gnome. The main difference being that Ubuntu wouldn't recognise my GPU and I had to install AMD's bash script (Which trashed the OS). Manjaro has no such problems, yet the main problem persists.
My $2,000+ AUD computer doesn't feel like a powerful machine that could do anything. Instead, it feels more like a buggy mess that could freeze at any second. Even if I only use Brave Browser, it still freezes about twice a day. When doing something like screen capture, video editing, or even just looking a pictures (gthumb), then at its worst, I'll have to do about 6 hard-resets per day. 'Snapping' a window to one side of the screen seems to be a guaranteed way of making the computer freeze up.
Computer Specs
CPU: Ryzen 3600 (Matisse ~ 7nm)
MB: ASrock B450 Steel Legend (Full ATX)
RAM: 2 x 8 Gb Corsair Vengeance RGB Pro 3200 Mhz
GPU: Radeon 5500 XT 4Gb (Navi 14)
HDD: Seagate Barracuda 2Tb
PSU: Corsair RM550x
Monitor: BenQ 1440p
AiO: NZXT Kraken X42
The motherboard by default limits the Ram speed to 2133 Mhz. I've booted Memtest and received no errors. Since then, I've changed the settings so that they run at their advertised speed of 3200 Mhz. Apart from that, I haven't overclocked or undervolted any of the components. The chassis also has a Noctua NF-A14 (140mm fan) for the CPU and the air-flow feels cool. When I learn how to install and use a suitable AUR program that substitutes the software provided by NZXT, I'll be able to check if the AiO pump is working or not. I want to do this before abandoning the Gnome ship. Is there something I'm missing?
