Hi jemonn ^_^,
Sorry for the delayed response. There are not many BSOD analysts so it takes time
I have analysed your dump files and below has been provided an analysis of the same for informative purposes :-
A kernel component has corrupted a critical data structure. The corruption could potentially allow a malicious user to gain control of this machine.
Let's check the stack -
Seems like the NVIDIA Driver (Which inturn causing Direct X to mess up) is messing up.

I see that you are using a LAPTOP. Regarding Video Drivers, in case of laptops, it is strongly recommended to use the drivers provided by the OEM of the laptop since they tweak the drivers so that it could work with the Graphics Switching. Graphics Switching is utilized by the OEM's to provide performance when required (Use your NVIDIA GPU to do tasks like playing Video Games) and provide battery life when the NVIDIA GPU is not being used (Use the Intel GPU to show the desktop).
So, I would suggest you to remove the currently installed NVIDIA Drivers using the Display Driver Uninstaller from this **LINK**. Once you have uninstalled the NVIDIA Driver, reboot the system. Once the system boots up, uninstall the Intel Graphics Drivers using the "Uninstall or Change a Program" which is visible in the ribbon when Computer is opened up.
Now, download and install the below drivers (Directly from Dell Support Website) -
NVIDIA Driver - http://downloads.dell.com/FOLDER0237...3.3165_A03.EXE
Intel Driver - http://downloads.dell.com/FOLDER0218...0.3574_A03.EXE
Let me know how everything goes ^_^
