Recurrent BSODs (KMODE, IRQL, SYSTEM SERVICE EXCEPTION) on new build

[Chivalry]

So I built a new pc on June the 2nd.
Specs:
CPU intel i5 4670 3.4ghz
Mobo Asus Z87-k
RAM 16gb corsair vengeance low profile ddr3 1600mhz CL9 1.5v
GFX MSI GTX 770 2gb
PSU Corsair TX650w (From OLD system)
Soundcard Creative Soundblaster Xtreme Gamer (From OLD system)
Storage 1tb and 640gb WD Caviar Black HDD (From OLD system)
OS: Win 7 SP1 fresh install

So here's a quick time line
build pc the first time; two faulty RAM slots that won't POST and turns out RAM is 1.65v which is technically not recommended so swapped for one above which is the recommended 1.5v for haswell cpus (further reading on this says 1.65v should work fine but trying to maximise compatibility here). Motherboard replaced as faulty. Problems were recurrent BSODs after and during fresh install of windows 7 of the KMODE_EXCEPTION_NOT_HANDLEd, IRQL_NOT_LESS_OR_EQUAL and SYSTEM_SERVICE_EXCEPTION with bluescreenviewer citing ntoskrnl.exe as the culprit (which it isn't). Memtest was clear over 12 passes. Hard drive diagnostics checked out perfectly.
Received the replacement gear and rebuilt but still got the same problems. RAM slots tested fine, Memtest is clear over 8 passes. Tried without sound card, still BSODs. Without graphics card, still BSODs. BSODs occur when idling, when trying to install drivers or when trying to install windows occasionally.
My current thoughts are it must be the only other component I haven't tested since I dont have another socket 1150 motherboard - the CPU. Kind of at my wit's end since I've tried the latest drivers, latest windows updates but it still bluescreens.
So what's everyone's take on this? The temps are fine by the way, this isn't overheating.

Minidump files attached.
Cheers.

I personally can't get anything from your logs, there are certainly no drivers showing up and it does seem to be pointing towards hardware. If you're suspecting the CPU, which it could well be, run Prime95 to stress test it.

Two things I would ask though is what copy of Windows media do you have, a DVD? It may be worth using an ISO from Digital River to rule that out. The other would be is your BIOS revision the latest?

Uh its Win 7 SP1 from a Digital River ISO usb bootable install.
BIOS is latest. Hadn't heard of that program but I'm not sure if it'd last long enough to stress it and be distinguishable as a CPU fault. Tends to crash within 5-15 minutes of idling or faster if i do something like install a driver or program. Will try though.
Cheers for the quick reply!
