Spontaneous BSODs, 0x7A and 0xF4 following 0xDEADDEAD

This really came out of the blue, but it all started within the past week. First there was the rare 0xDEADDEAD, which, after some quick googling, it seemed that the Intel wireless driver was the culprit. Updated that, and then the crashes turned into 0x7A and 0xF4. Nothing really triggered them, once they happened when I was using Chrome, another in Skype, and another when I was just trying to defragment.

Only problem is, none of them actually generate a dump, as far as I know. Every so often it will say that it failed and give me the code "0xC000009C" for not generating it, while paired with a 7A or F4.

I'm planning on running a memtest later on the day, and I've tried a few scans with MalwareBytes and Kaspersky. Both of them can't finish a full scan without having my computer crash, though.

Here's what I got from CrystalDiskInfo. I'm running the hard drive test right now, and I'll post results when it's finished.

Okay, here's an update. Most of the tests I tried to run couldn't finish without a crash. The disk check got to about 50 percent until I looked at it and saw a bluescreen. Plus side is, it was finally able to come up with one dump in the middle of it all. It is attached.
Going to run a memory test now.

Okay, how old are the hard drives?

I bought this last year, in October. So probably not that old. Is there a way to accurately check, though?

Okay, wow, I think that worked. I ran some memory tests and nothing came up after many passes, I ran some short tests (as to not crash the computer) got an error, ran the SeaTools for DOS, and I think it's repaired now. I'll run some more tests to make sure it's good and check if I actually crash more.
