Windows 7: BSOD IRQL_NOT_LESS_OR_EQUAL ntoskrnl.exe While under heavy load

BSOD IRQL_NOT_LESS_OR_EQUAL ntoskrnl.exe While under heavy load

I've been getting these crashes since day one of putting the pc together and over the years and picked at it trying to figure the issue. I use to get the IRQL_NOT_LESS_OR_EQUAL ntoskrnl.exe bsod a lot and traced it back to a driver issue over a year ago but continued getting other crashes, I cannot for the life of me remember what or how I figured it out the last time.

Recently my drive had be getting a bit full so I got a new 2t drive to use as game storage, put everything I wanted to keep on the new drive and reformatted my old 750 gig drive to use for windows and miscellaneous files. Right after the install I immediately began getting the old bsod error again and have been unable to track it down. So far I have attempted updating all drivers I could think of but I'm out of ideas and I apparently dont know how to track down these issues as well as I had hoped. Hopefully someone who knows what they're doing better then I do can lead me in the right direction.

So far all of the crashes have happened when the system was under heavy usage. Examples, playing a graphic intensive game for over an hour, downloading multiple large files, transferring several gigs of data from one drive to the next.

Any help at all would be very much appreciated, Thank you in advance.

Sounds like bad RAM to me, you have Driver Verifier enabled and it still hasn't picked anything up.

Memtest86 will test your RAM

information   Information

Run Memtest86 for at least 8 passes so we get enough information to confirm that your RAM isn't failing

Just finished a 38 hour 10 pass memtest run, no errors.
I ran memtest back when I first started trying to figure this our over a year ago, didn't have any issues then either.
I have also recently run Western Digital's Data Lifeguard and as well as an asus pc stress test utility for an hour and found/had no issues.

Have you had any new crashes?
If so upload the dump files, lets see if anything different pops up.

I haven't had any new crashes, they suddenly decided to stop as soon as I actually want them to happen. I'm going to be out of town for a few days and wont be using my pc. But when I'm back and it crashes again I'll upload a new report.

After all this time the pc finally crashed again, this time just playing a video via web browser. Though this time the string reported SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION. I've never gotten that string before today. Regardless of if its related or not I've uploaded a report.

Ran Memtest again thinking maybe something got damaged but again it didn't turn up with anything. I've been repeatedly having crashes with the SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION string report.
