One of my computers often boots and stops with the following screen. I can't even get to the BIOS when it happens. I am hoping to rectify the problem.
How can I isolate the USB circuit on the motherboard?
How can I be sure this is the motherboard problem, not the processor, so that I can get an appropriate replacement? I have been looking at the BIOS to find out if I can turn off the USB's and see if it would fix the problem. Having done so I hope I can add a PCI card with additional USB ports as replacement.

I suspect the built-in USB circuit on the motherboard faulty. This is an MSI mother board.
When it boots successfully like what happens right now I can see an unknown device from the Device Manager. Such unknown device didn't exist before when the system worked alright. Once the system boots, everything seems to work fine including the USB ports. From then onwards the system would seem to boot fine until I stop having it turned on for a while.
It is also quite unusual to me that there is some hex number at the end of every line as set out below. They look like memory addresses to me. I don't remember seeing them on other Windows systems.
