Ethernet and USB 3.0 ports suddenly shutting down

What the title says, these shutdowns can occur semi-randomly, although they seem to happen more frequently when rendering on blender or playing minecraft.

Would this happen if you stress tested your cpu or gpu? Could you try? Because the blender and minecraft mentions are weird

I put the cpu under pressure for 5 minutes using stress-ng, no disconnections happened, so i don't think that's the cause

Just curious because you mentioned it only shutting down when under stress of rendering Blender or playing a videogame. Could you monitor your temps during such activities? Just to rule out a thermal issue. Also do you see anything in dmesg or any crash logs?
And does stress-ng also work the GPU?

I found this online, just in case. Your same motherboard, too, I believe.

On thermals, highest temperatures my CPU reaches are in the 50 degree area, going up to 70 when using stress-ng, which doesn't strees the GPU, however, I don't believe it's a gpu issue, since games like Ultrakill and source games run just fine, only game with issues is minecraft, and it happens when it loads the main menu, also i haven't used armoury crate so i don't believe that's the issue either
