Random BSODs - minidumps not being created, only full memory dumps

[nutidizen]

Hello,
I'm struggling to find out the cause of these BSODs. I can't figure out why the pc doesn't want to create the minidump files, only full memory dumps.

PC:
Intel i5-4670
Nvidia GTX660
MB MSI B85-G43
RAM 2x4GB Kingston KVR16N11/4

First BSOD happened when browsing the internet. Bugcheck 0x1e (0x0, 0x0, 0x0, 0x0), WinDbg shows analysis_inconclusive... So I decided to try turning on Verifier.
Highly compressed (137 MB) memory.dmp here: https://drive.google.com/file/d/0B_XW8op3P2-5a0x5em4tckhtRFE/view?usp=sharing
If you don't want to download the whole file I tried to create a WinDbg analysis here: http://pastebin.com/raw.php?i=KALwHrv2

Then the second BSOD happened, again random when watching video. BugCheck A (0x0, 0x2, 0x0, fffff800030957d5), sadly the BUCKET_ID says: INVALID_KERNEL_CONTEXT, unknown image module...
Highly compressed (54 MB) memory.dmp here: https://drive.google.com/file/d/0B_XW8op3P2-5LUlqVXhLQWJMaG8/view?usp=sharing

I'm afraid this could be a CPU HW issue...

Thank you very much for any help!

P.S.: The computer is not mine, so getting some additional info could be a problem but I will try to do my best.

Minidumps will be good o get easily.

Go to Option Two, Point 2. Download the .reg file and merge it in registry by double clicking it.

Now wait for another BSOD. When it occurred, search the .dmp files manually in the default path: C:\Windows\Minidump or %SystemRoot%\Minidump. See if the crash dump is recorded or not (hopefully it will be recorded).Post it following the Blue Screen of Death (BSOD) Posting Instructions.

A stray minidump will not lead to anything, unfortunately.
