Solved BSOD trouble identifying issue, WHEA error!

[Observer101]

Hello, specifications are linked to the same profile as I am writing with. I've had the Blue screen of Death for about 5-6 months with my custom PC built around 1 year ago. At first I presumed the BSOD HAD to be software related as I have not tampered with, overclocked or damaged the hardware, all hardware is genuine and bought brand new. However since re-installing windows 7 twice while formatting the hard drive, it would be safe to assume and come to the conclusion that it is most probably a hardware related issue. Using "who crashed" the dumps would be different, some stating memory management, bad pool header, IQR not less or equal etc etc etc (These errors were on the original and first ever installation of windows 7 and the first re-install, not second). Unfortunately as I mentioned previously I've re-installed windows 7 twice, after the first encounter, this being the twice with the old dumps having been completely deleted and erased. Since installing Windows 7 the second time only after a few days, I have received the following error, "WHEA_UNCORRECTABLE_ERROR
" 4 times consecutively with all the crashes since re-download stemming from this. crash dump file: C:\Windows\memory.dmp
This was probably caused by the following module: hal.dll (hal!HalBugCheckSystem+0x1E3)
Bugcheck code: 0x124 (0x0, 0xFFFFFA800AAFB028, 0xBF800000, 0x200401)
Error: WHEA_UNCORRECTABLE_ERROR
file path: C:\Windows\system32\hal.dll
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: Hardware Abstraction Layer DLL
Bug check description: This bug check indicates that a fatal hardware error has occurred. This bug check uses the error data that is provided by the Windows Hardware Error Architecture (WHEA).
This is likely to be caused by a hardware problem problem. This problem might be caused by a thermal issue.
The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.

More background information, Since re-installing Windows 7 Pro for the second time I assumed the BSOD had been fully eradicated and the Online download of Windows 10 would work. Keep in mind I had tried to download Windows 10 before this current build of windows 7 I have right now (The first re-install), but it would crash on the final segment of "copying files" around 30-40%. Windows 10 download commenced, installation, verification, updates, installation everything worked. When it ended up going to the last portion of installation where it copies files, downloads drivers and so on it crashed again on 30-40%. That's when I re downloaded who crashes and saw the WHEA error for the first time, I tried to downloading again several times with the same crash during the same sequence of windows 10 download. During the original installation of windows 7 and the 1st re-install, whocrashesd also came to the conclusion that the third party driver of "nvidia kernal mode" was responsible for the BSOD, however I completely deleted all applications, registries etc etc, redownloaded Nvidia and the issue persisted on.
Also Power supply is a cooler master 750V

UPDATE:
Using BurnInTest, I individually stress tested each component, one stood out... ram. Critical errors emerged and I removed one 8GB ram stick leaving the last in and repeated the same test, no errors. I'm re-downloading windows 10, if it works and the problem doesn't re-emerge I guess that was the problem and fix, update soon!

Windows 10 fully installed without a hitch, returned to computer store and under warranty returned the two modules of ram and received another two modules, (Kingston HyperX 16GB ddr3 ram [BLUE]) for free, FIXED!!
