BSOD New build, Random times, multiple stop codes

I have mostly a new build. The CPU, Mobo, SSD and GPU are all new. The RAM and PSU are taken from a previous build, but only a couple years old.

I have had problems since I got this build together. I get random crashes or freezes. Sometimes it happens every hour, sometimes I can go a couple days without one.

I have run Memtest overnight with no errors on this mobo and the previous one, and Windows Memory diagnostic with no errors all day long, so I think I can rule out the RAM.

The SSD has never reported any errors in the Seagate tool.

The CPU passed Prime95 and the intel burn test.

I have not really stressed the GPU outside of some newer games on max settings (Wolfenstien, Watch Dogs, Murdered).

I recently updated my mobo to the newest firmware (it was just released about a week ago I believe), but it hasn't helped.

I have tried this system on Windows 8.1. I was getting random freezes, but I would never get a dump. I switched to Windows 7 and now I get dumps, but still cannot diagnose this problem.

I uploaded the sevenforums diagnostic tool results. The latest dump should be with driver verifier running. It took a while to crash, I was surprised.
I don't seem to get BSODs, just the computer kinda force shuts down and restarts and I have a new dump.

Please help me.

Build:
CPU Intel Core i5 4570
MOBO MSI H87G43
RAM 4GB x2 G.Skill Ripjaws
SSD Samsung 840 EVO 500GB
GPU Gigabype Radeon R290
PSU Corsair HX750

Yeah. I used Samsung's magician as well as checked the firmware version on the site. It came shipped with the latest firmware.

Yeah. Usually daily. I'll post my latest dumps when I get home.

Here is the newest zip of dumps.

These are weird crashes. It basically forces a restart. Usually the sound will quit, then the computer kinda just shuts down. It often happens while watching flash videos, but not always. I can still move the mouse and switch to other open windows for about 10 seconds. Then when it restarts, I get the "Windows has recovered from an error" and there is a new dump.

Also, thanks for taking a look.

Got another one.

Sure thing.
