Hi Arjorn & Welcome to the forums ^_^,
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).
So, according to the dump file, a DPC (Deferred Procedure Call) or an ISR (Interrupt Service Routine) took longer than it was supposed and hence the system crashed.
Let's take a look at the stack -
And the driver hanging up is the NVIDIA Driver.

Kindly uninstall the currently installed NVIDIA driver using the Display Driver Uninstaller from this **LINK**. Once the driver has been uninstalled, kindly reboot the system. Try installing a BETA driver and see if the problem resolves or not. If it is not resolved, try a driver from few versions earlier. You could also try the driver which came with the Graphics Cardin the driver disc.
Let me know how it goes ^_^
