Constant BSODs, can't find a pattern

For the last week or so I've been having persistent BSOD issues. Its fairly sporadic, I had only one yesterday in about 10 hours of using the PC, but 4 this morning in the space of about 3 hours. I've used programs like Blue scren viewer and Whocrashed to try and find a pattern but the error code is often totally different. The only one that comes up more than the others is MEMORY MANAGEMENT. Here are some that I've written down:

-Multiple IRP complete requests
-Bad pool header
-system service exception
-DPC Watchdog violation
-page fault in non paged area dxg kernel
-PFN list corrupt
-IRQL not less or equal
-Kernel security check failure
-Memory management
-Driver overran stack buffer

Since I upgraded to Windows 8 6 months ago, then 8.1, I would get a BSOD roughly once every two weeks. In the last week its suddenly ramped up x10. I haven't installed any new hardware in about half a year either. Can someone please help me find a pattern or connection
between all these, as every analysis program and debugger I use points me in many different directions with each different BSOD. The only thing that comes up often is ntoskrnl, but I've been told that doesn't necessarily mean much in itself.

Things I've tried already:
-Ran windows memory diagnostics overnight, came back clean
-Full antivirus and spyware scan
-Have used multiple driver utility programs which say that everything is fully up to date.
-Tried to use driver verifier, but BSOD'd the system on boot without giving any information. Took me ages to get rid of it.

If anyone could help I'd be very grateful. Here are some crash dumps (unfortunately it didn't generate dumps for all of them)

You can try to monitor your system temperatures with HWMonitor to find out if its a temperature related issue. Also you can try to use WhoCrashed, to see what specific hardware was causing your constant BSOD crashes.
 
I recently rebuilt my PC (Motherboard & CPU) & now get this same error - my most common is Kernel Security Check Failure. All indications are a conflict with my AMD R7800 GPU & I'm currently running a driver from 2014 which SEEMS to be working....
Anyone have any ideas?
 
@maggiechow Sounds like a failing hardware issue and I would agree with Cobalt006 on use of Memtest. The BSODs date back to original install of Win8? Did you change hardware?

@Peter11 Perhaps you should start your own thread. I think the issues are different.
