Set the time before you start.
When its done, pass or fail, it will make some graphs. Post these here as they are useful for analyses.

Let us know the results.
Here's that test run for 30 minutes (1 idle at beginning, 5 idle at end):

The graphs look good except for the Vcore, it's at 1.21v at idle and 1.175-1.87 under load.
It should be below 0.900v at idle and 1.20v under load, it's reversed itself and not giving the correct voltages.
Noticed this in your CPUZ snip, and your post 'CPU Vcore: 1.225v [Auto] (this, of course, flucuates)', wanted to confirm it.
Your CPU frequency is 3.3GHz under load, Turbo should be 3.7GHz. Did you disable Turbo in the BIOS?

Have you changed any BIOS settings before the changes I requested?
If your CPU Vcore on 'Auto' is not giving you the correct voltages, this can cause system instability.

Let's check the BIOS, if it has been corrupted.
You can use your Dual BIOS, check the CPU Vcore voltages.
Or:
In your BIOS 'Set to Load Optimized Defaults', save and exit.
Clear CMOS
Go to BIOS and 'Set to Load Optimized Defaults', save and exit.

You can use either method below to clear CMOS.
Page 30 of your motherboard manual.
Quote:
17) CLR_CMOS (Clearing CMOS Jumper)
Use this jumper to clear the CMOS values (e.g. date information and BIOS configurations) and reset the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two pins for a few seconds.
• Always turn off your computer and unplug the power cord from the power outlet before clearing the CMOS values.
• After clearing the CMOS values and before turning on your computer, be sure to remove the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.
• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS configurations).
Page 24 of your motherboard manual.
Quote:
You may clear the CMOS values by removing the battery:
1.Turn off your computer and unplug the power cord.
2.Gently remove the battery from the battery holder and wait for one minute. (Or use a metal object like a screwdriver to touch the positive and negative terminals of the battery holder, making them short for 5 seconds.)
3.Replace the battery.
4. Plug in the power cord and restart your computer.
•Always turn off your computer and unplug the power cord before replacing the battery.
Open CPUZ, check the CPU voltage at idle.
With CPUZ open, start OCCT for a short test, check CPU voltage at load.
Then test for stability, this may solve all of the previous issues.
Let us know the results.

When you mentioned the voltages reversing under load and idle, it brought back a recollection of when I was experimenting with overclocking on this box. At the time, I had to use the CPU Multi-Step Load Line to correct the Vcore voltages. Set at Level 4, it kept it at the necessary voltage to keep the system stable (at least, from what I recall). I believe I reverted back to stock settings as it was hitting summer and I wasn't too pleased with the temperatures I was seeing on the CPU. In any case, I had left the Multi-Step Load Line activated and still set to Level 4.

Realizing this, I went back into BIOS and disabled that setting. A test in OCCT showed the voltages in the Vcore acting more proper: low when idle, fluctuates in general use, higher and at a peak when under full load.

At this point, I figured it possible the problem was resolved. Two days of heavy usage and no blue screen. Of course, if I'm making this post, that means something went wrong.

Today, from a cold boot, just after I log in to Windows and everything (which is, not much) is still loading, BSOD. Code? 1e. Comedy.

(dump attached to this post)

So, after a reboot and creating a dump, I also did a 40 minute OCCT run. I'll add them here to see if they're of any use.

My next step will be clearing the CMOS and resetting the BIOS, a step I wanted to avoid doing as there are certain settings I'll need to put back in place (motherboard ports I don't use, onboard audio to disable, hard drive order, etc.). However, at this point I'm really starting to think it's some hardware failure, and I'm almost hoping it's the RAM so I can just get that replaced and end this hassle. Though, if something else can be done to not require that, that would be nice.

Check all of the BIOS settings you want to change later, good idea to keep a BIOS settings template (list of your preferred BIOS settings).
Re-set the BIOS to Optimized Defaults, re-boot.
Shutdown, Clear CMOS.
Re-set the BIOS to Optimized Defaults, re-boot.
Then make your changes.
You can save the setting in BIOS, on the BIOS Save & Exit page, there should be a Save and a Load option.

Your CPU frequency is stationary at 3.31GHz, it should be going to 1.6GHz when at idle.
This is why I would re-set BIOS to optimized defaults, it will clear any other settings that may be causing issues.
BIOS settings can and will cause many issues if they aren't set correctly.

Last crash:
Code:
KMODE_EXCEPTION_NOT_HANDLED (1e)
This is a very common bugcheck.

Appears to be RAM caused, re-set BIOS settings first and we'll look at it again.

Did this in the order stated (and confirmed CMOS reset by seeing that ugly Full Screen LOGO that I always disable), made my changes, and the results are... curious. Note that the only BIOS changes I made had to do with Integrated Peripherals and Advanced BIOS features (Hard Disk Boot Priority, Boot Device Order, disabling Full Screen LOGO and changing Init Display First to PCIE x16). Everything else - all memory timings, CPU settings, etc. - were left at their default settings that the loading of BIOS Optimized Defaults set them as.

The Vcore is still acting more proper, but the core speed is not dropping to the much lower mark it should when idle (it used to do this, I recall, many months ago). The multiplier also seems to be defaulting to x34, with Turbo active thus fluctuating up to x37 at times. Any idea as to why the lower-idle speed (Intel's C1E, I believe it's called) isn't kicking in?

In addition, here's a quick seven minute OCCT test I ran after doing the resets. I'm no expert on voltages, but compared to my previous tests some look a bit... strange.

Check that your Power Options are set to Balanced and not Performance.
The lower idle speed is called 'CPU EIST Function' in your BIOS. This should be set to Auto by Load Optimized Defaults.

The CPU frequency seems to be going from 3.7 GHz before the test starts, this is normal single core frequency, and then going to 3.5 GHz when the test starts, this is normal 3&4 core frequency.
Vcore is getting high voltage spikes because the idle frequency is 3.7 GHZ instead of 1.6 GHz, the CPU useage is normal.

Seems like EIST is not working, check the BIOS setting.
If it is set to 'Auto' and not working switch to your secondary BIOS, re-set to Optimized Defaults and test it.

Preemptive tl;dr: no blue screens in a week. Now, for the explanation and current status:

When you mentioned Power Options, I checked for it in BIOS, but could find nothing. However, with that mention, it made me think of the Power Options in Windows - which made me consider the EIST not functioning properly could be on Windows' end.

I remember altering the Power Options when I first installed Windows 7, as it had a tendency to turn off my hard disks after some time, which became very annoying very quickly. However, I didn't touch anything else, and never visited the options again.

Some research later, and I discover the Processor power management in the advanced settings had a different default setting to what it had at the time. Default, the Minimum processor state is 5%, which is what mine had to be at one time. For whatever reason, my custom settings had it at 100%. The only thing I can think of that would've caused this is, when I did the beta video card drivers update back in November, I probably also did a Windows update at the same time. It's possible that in this update, it changed my custom power plan. Not sure why, but that's the only thing I can think of.

Anyways, I changed the Minimum processor state to 5%, went back to BIOS to switch everything back to auto and defaults - along with turning off Turbo for the purpose of this test - and checked it. Result: EIST seems to be acting normal; the CPU's core speed being in flux, and highest when under full load.

After week of it set like this, and no blue screens, I'm thinking this was probably the problem - the voltage would drop when idle or not under full load, but the CPU would stay at the static core speed.

I did an OCCT test after a cold boot today. I'll post the results below. After this, if nothing looks out of the ordinary, I think I'll test with getting the RAM back to the desired 1600 speed. For now, glad to at least have the system stable (or so I hope, knock on wood).

To my eyes, everything looks correct here, except for the +VCC and VCC3 dropping in voltage some when under full load. It's not much in the way of voltage, but I just want to check to see if it's normal.

Nice work, that could explain the issues you were having.
These graphs look better.

Let me what BIOS settings you are going to change to get the RAM at 1600MHz.

Currently, I'm testing the system with Turbo re-enabled (so far so good). I think tomorrow I may set the RAM back to 1600. What settings would you recommend I change to do this?

Set your RAM frequency manually to 1600MHz.
Also set the first four RAM timings manually to 9-9-9-24 and the 'Command Rate' to 2T, leave the rest on 'Auto'.
Test for stability, memtest86+ for 7 full passes.

Let us know the results.
