Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

First run it with all the existing/installed RAM modules. If it comes with no error, all is good.

But if it starts showing errors, Stop testing. Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:
It is a RAM, a bad RAM.

But if you have got a result like that:
It is a motherboard issue. The particular slot is bad.

Thanks Arc. I'll work through this list over the weekend.
I have run memtest86+ for 8 passes twice with no errors in the past. I've also run the video test before, and I have just replaced my graphics card. Seeing that the symptoms pre-existed my new graphics card, I think it's logical to rule that one out.

But it doesn't hurt to double-check. I'll report back my results.

Computer crashed again, and no dump file (with verifier running).
I took a snapshot of my computer temperatures via Speccy, attached below.
I will work through the rest in the coming days.

Just a quick question without re-reading the thread, though I have been following it:

Have you reinstalled sticking closely enough to the steps to get a perfect install compiled in Clean Reinstall - Factory OEM Windows 7 (same for retail)?

To do this I would first test the HD and RAM from Troubleshooting Steps for Windows 7 then wipe the HD to get the cleanest slate using Diskpart Clean Command.

Hello Greg,

I appreciate your advice as well. I have doubts it's my hard drive, considering that I just replaced that earlier this month, and as with my graphics card replacement, I've had these exact issues since before their replacements. That said, I'm happy to leave no stone un-turned. I will try it out, and report back.

And yes, I followed those steps for a clean reinstall :)

I see Archie is concerned about your RAM test. Can you run it for at least 5-6 passes or overnight to stress test it?

When you reinstalled did you use only the drivers provided by installer and updated during all rounds of Windows Updates?

Which drivers were still missing after all UPdates were done and where did you get them?

I plan on running the memtest overnight tonight for at least 8 passes, so I"ll report back tomorrow.

When I reinstalled, I updated my Chipset drivers first, then my LAN drivers. I obtained the recommended drivers from my motherboard website, and then I went to the individual driver websites to get the latest. I did these first so that I can have access to internet. I then used Windows to update the rest of my drivers (windows was the one who found and installed my bluetooth driver, btw). The only other two drivers I manually updated was my graphics driver (from Nvidia's website), and my audio driver (also from motherboard then actual manufacturer's website).

That is not how drivers are best handled in Win7, the first driver-complete OS. Read Steps 9 and 10 Clean Reinstall - Factory OEM Windows 7.

I must be very thick, but I read through those steps, and they seem to correlate what I did?
1) After install connect to internet (install LAN driver if necessary; I was under impression I needed to install chipset driver in order for LAN driver to work). Are you suggesting the chipset driver is completely unnecessary?
2) Then connected to internet for further updates and used them install all the missing drivers.
3) Then graphics + audio from manufacturer's websites.
What are you suggesting that I did improperly?

Sometimes Win7 will give you a chipset it wants, is all. So installing chipset first can cause problems. The LAN should work without it, provide you what you need once you enable Automatically deliver drivers via Windows Update (Step 3) and run all rounds of Important and Optional Windows Updates.
