Question Usb and ethernet on motherboard disconnect after 3-4 hours of use

[DemiseJ]

Specs:
Rx 580
3200g
Prime B450m-a (newest bios update didn't fix)
Cooler Master MWE 550 Bronze
Toughram RGB 3200 2x8 gb

This issue seems to be accuring when there is less use of the graphics card/cpu
Like when im out of a game

Thanks for your help.
