As a test, could you install versions 390.65, 388.71, 388.59 and 388.43 of the nvidia display drivers.
Install 390.65, if you experience a DPC_WATCHDOG_VIOLATION crash, install 388.71. Do this 'til the last driver.
If there are no crashes, don't move onto the next driver and let me know.
if there's a different crash, let me know by providing new dumps.
