The Nvidia Video driver has been flagged, but also a Windows USB driver has been flagged.
Please try to connect the new keyboard to another USB connection and see if the problem persist.
If the problem persist, then most likely the keyboard connection is faulty.
If the problem doesn't persist, then I recommend to connect a device where you know from that it should work in the same connection as where the keyboard was connected with the crash, to find out if the USB port is faulty.
Probably caused by : USBXHCI.SYS
Let me know how it goes
