Hi Ryan & Welcome to BC ^_^,
I have analysed your dump files and below has been provided an analysis of the same for informative purposes :-
The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL or above.
Arg1: 0000000000000000, A single DPC or ISR exceeded its time allotment. The offending
component can usually be identified with a stack trace.
Arg2: 0000000000000501, The DPC time count (in ticks).
Arg3: 0000000000000500, The DPC time allotment (in ticks).
According to the dump file, we see that the single DPC or ISR (Interrupt Service Routine) exceeded the time it was allotted to perform it's job. The amount of time allotted is highlighted in BLUE color.
Now, let's take a look at the stack and see if we can find the suspect -

We see that the NVIDIA Driver was trying to acquire a spinlock but since it did not get it after some time, the DPC Watchdog which keeps track of such activity decided to crash the system.
If the system gets "Display Driver has failed to respond..." for like 5 times in a small interval, Windows decides to crash the system with the bugcheck which you are experiencing.
Kindly uninstall the currently installed NVIDIA Driver using the Display Driver Uninstaller from the below link -
Once the driver has been uninstalled, reboot the system.
After the reboot, try installing the driver from the Driver Disc which should have come with the GPU. If you cannot find that, try downloading an older version of the NVIDIA Driver and see if the crashes persist or not. In some cases, it has been observed that such kind of crashes are often resolved by installing the latest BETA Drivers from NVIDIA.
Let us know how it goes ^_^
