Frequent BSODs: Page fault in nonpaged area, IRQL not less or equal

[violapower]

Hi,
Over the last couple of months I have been getting BSODs of a variety of types. The last two I recorded were IRQL not less or equal (when disconnecting the external monitor) and Page fault in nonpaged area (when connecting the monitor). I am not sure whether connecting/disconnecting the monitor is relevant, as previous times I got BSODs without that (e.g. system service exception). A number of the times were when I restarted the computer. I am attaching shots I took of the screen on my iphone. Apologies for the quality.
Similarly, I did not understand from the instructions how to "save the information into a debug-YourComputerName-xxxx.zip file on your desktop". I hope have attached the right thing.
Thanks for you help!
