Borrow a known good PSU of the same wattage or greater and swap it in there...

Total Cost ?  = $0.00

    I hope it was this easy.. As far as I know, unfortunately there are no shops in my place that could actually 'rent' out a PSU or someone who could agree to have their PSU swapped/borrowed for testing purposes...  :'(

      I really dont understand what is the problem involved in having the driver (ntkrnlkpa.exe) file that is responsible for all the trouble, diagnosed..!
      Is there a possibilty that dahlarbear who gave me that suggestion would be able to check it out?

      The problem is that there is no problem with the driver to begin with.

      There is nothing wrong with the driver.

      There is nothing wrong with the driver.

      There is NOTHING wrong with the driver.

      If there was something wrong with the driver, everybody would know about it, because nearly everybody has ntkrnlkpa,exe, win32k.sys, and many of the other driver files that were named in your blue screen errors.

      this is NOT the fault of a single driver (the "single driver theory" reasons I stated above were wrong... turns out if a driver tries to write to an area of memory if doesn't have access to it would fault itself, not another driver). and the error codes and the files that are causing the issue point to an issue on the hardware side, since they completely random. This in addition to the fact that the issues persists across two installs points directly to something wrong with the system itself, and the fact that the issues are so random and intermittent puts a spotlight on the PSU as the trouble-maker.

      In fact, of the possible causes (motherboard, CPU, and PSU) the Power supply is the cheapest.
      I was trying to dereference Null Pointers before it was cool.

        Either replace the power supply or watch the video again and again until you understand it.  Clearly you missed several key points...

        Core Windows files are "rarely" responsible for a crash, e.g. "ntkrnlkpa.exe" (unless they are "corrupt"); because they are thoroughly tested by Microsoft.  When blue screens identify several different modules, it's either power, hardware, (not sure about heat), or another driver that is corrupting the memory space or data structures of the blue screen modules.  The modules named in your blue screens are probably not the underlying cause; they are the "victims".

        You want to target the underlying cause, not the "victim" drivers.  While it's not necessarily wrong to "verify" the victims, that only confirms what you already know.  They're faulting.  You need to catch the driver behaving badly before another driver comes along and trips over its corrupting influence.  The video illustrates how you may use driver "verifier" to do this.

        If your diagnostic testing indicates blue screens only occur when your network software is "active", then take a closer look at the network drivers.
             a.  Are your network drivers "signed"?
             b.  Are they the correct driver for your operating system?
             c.  Are there "updated" network drivers available?
             d.  Are you using a "wired" or "wireless" network adaptor?

        Take a look at your security software.  Many of them operate at a low level within the operating system (and actively screen network input/outputs).  You could use "msconfig" to perform diagnostic startups (selectively disable "non-Microsoft" security software applications and services).

        Perhaps you should boot to "Safe Mode with Networking" to test.  In this mode, most if not all of your security software is not started.

        Or you could replace the power supply...  Expensive I know, but it might resolve your issue.

          Finally, got my PSU replaced with a cool 500w one... about a 40$.. quite a decent well known brand here in my country...
          Following this, I will perform a clean install of my OS, observe and post back the results..

          Thank you all for the advice offered.. :)
