Both the crashes have been caused by the Conexant audio drivers.
Check Dell for driver updates or reinstall the drivers.

Thanks for the follow up on this. The driver has been updated. However, we have run into another BSOD. This time the only known is that is happened on a Saturday when no one was on the PC. The debug info is below and the log collector files are attached.

Either Windows Update has installed a different version which downgraded the driver or the driver isn't updated.
Same driver causing the crash, same driver date.
