I note that the chipset on your motherboard appears to be faulty, which explains the lack of functionality for USB ports and the Ethernet connection (you're using a PCIe Express Ethernet card). This information is relevant and may be necessary for troubleshooting. Your system specs include a Ryzen 5 3600X with an X570 GPU, 4000MHz RAM, and custom timing set via the Ryzen Timing Configurator. The motherboard is MSI B550 Gaming. Temperatures are within normal ranges. A video has been attached that details your issue and highlights an unusual screen behavior when switching tabs. Any assistance would be appreciated.
Reduce the frequency to 3600 and observe whether the problem resolves. If the infinity fabric appears too high on Ryzen 3000/5000 processors, it may lead to unusual performance problems similar to what you're facing. Not all R5 3600X models will run at 1900MHz FCLK, so lowering it to 1800MHz—something every CPU should do—should likely help. Another potential cause could be background overlay software or programs, which sometimes trigger stuttering behavior, though these are less common today.
It might suggest RAM speed instability triggered the BIOS to reset to 2666 MHz and revert to default settings.
It seems like the issue might be resolved by keeping the RAM settings at their default values and checking if the problem persists.
