Kbdclass.sys Connected to a device driver for a keyboard. Note: Make sure to read and remember the steps to reset DV in the event of a crash, then collect and upload the newly generated crash dump, and post the shared link here. most likely from the old motherboard sound driver responding to the sound requests from the gpu sound driver.
