Windows 7: Various BSOD's, all connected to ntoskrnl.exe+74ec0

Windows 7 Ultimate x64
Various BSOD's, all connected to ntoskrnl.exe+74ec0

Hi, I am completely new here and don't know if I am at the right place, feel free to correct or move me if I am not. Also English is not my native language, however, I prefer to discuss computer problems in English as it is much easier to find additional information. I will try to express myself as adequately as I can.

So, for the past 3 weeks I have been getting BSODs at completely irregular and random intervals, sometimes none for 5 days, sometimes 4 in 2 hours, and I have officially ran out of ideas what to do.

It all started 1 day after I got a new monitor, though I have no idea whether that is a coincidence or the monitor is to blame. The first one was a bad pool header, the second memory management, by now I have had at least 6 different ones, but you can see all in the crashdump files which I've zipped and linked at the end.
Anyway, since I'm not lazy, I tried to fix it. And boy I tried... So far I have:
-Updated Driver
-Ran checkdisk
-Formatted my Hard drives and re installed windows (that helped for about 2 days..)(*note*: I did not format C manually, where I Installed Windows, as I gave it the command to format it himself, might be an issue?)
-Updated all drivers again
-Got kaspersky Antivirus and checked everth.
-Ran windows memory test and memtest86 (0 errors)
-Changed monitor cables to be both DVI (since my Graphic card is known to give BSOD if you use both HDMI and DVI at same time)
-Updated Bios to newest
-Ran CHDSK and updated drivers...again
-Prayed to various deities

And nothing of this had any lasting effect. I keep getting jolly BSODs whenever they please. Sometimes after a browsed crashes. Sometimes while i Install something. Sometimes on Boot up. Sometimes when I start a game, or a game crashes. Sometimes when I Alt-Tab too frequently. I am officially out of ideas what else I could do. If someone suggested me that strapping my PC to my chest and go paragliding would fix it... hell I'd prolly give it a try.
*Note: Lately, I have been getting an immense amount of critical Errors in games. Much higher than I used too. It usually happens when I either start the game, Alt-tab back to a game, or have a loading screen in game. Almost never when the game is running. On rare occasions exactly these crashes are followed by BSOD. Might this be related? I am a total newb in such issues, but that would sound like hard drive/Ram issue to me.

Here are the crashfiles: -

That is exactly what the tutorial is designed for. We do not want a intermediary we have to go to who know where.

It is more secure to do it as per the tutorial for members that want to help you.

Given the type of installation, the best i can suggest is to run a minimum of 8 consecutive passes, preferably overnight, or until errors occur using MemTest86+ and see if its a RAM issue.

Counterfeit installations such as yours contains heavily modified code that causes the installation to behave it unexpected ways. Analysing BSOD's and determining their causes on these sorts of installations is very unreliable.

My recommendation is to start with a clean slate, and install a genuine version of Windows. This will minimise the problems you are experiencing, and make subsequent diagnosis of BSOD's far more reliable.

Installation should actually be genuine, only activation code not (original lost somewhere in the oblivion of moving). But I can just reinstall from the University servers, will get to it ASAP.
