IRQL_NOT_LESS_OR_EQUAL BSODs during boot, during driver installations, and other times.

[pikagrue]

System specs:

* Intel Core I7 6700k Skylake
* Gigabyte z170xp - SLI motherboard
* 16 ram gb
* GTX 980
* EVGA 850w PSU
* Intel 480 GB SSD
* Toshia 1TB HDD
* Razer Chroma mouse
* Corsair k95rgb mechanical keyboard
* Generic asus monitor
* Windows 10 64 bit

Symptoms:
Installing DX11 fails.

Steps taken:
Removal of GPU and letting Windows run (still crashes), full reformat and reinstall of Windows 10, and it still crashes on boot afterward. Spent an hour testing RAM with memtest86. CPU test OK (intel software), GPU test OK (futuremark), HDD tested OK, SSD tested OK (both with Seagate tools). Have tried uninstalling and reinstalling nVidia and Razer drivers, but it usually crashes when installing drivers.

Your Nvidia drivers conflict and DX install fails because of this issue, either the driver is corrupt or just is incompatible , try an older or newer version or redownload that one. Using DDU to remove those old drivers? http://www.nvidia.com/Download/Find.aspx?lang=en-us latest is 368.22
Make sure you install the motherboard drivers/bios (bios F6) too http://www.gigabyte.com.au/products/product-page.aspx?pid=5496#dl

I've used DDU to uninstall and attempt to install nvidia drivers multiple times. Every single time, the computer would crash mid installation with the same IRQL BSOD. On the last installation, it was able to reach near the end of the installation process, but still crashed. The drivers installed still kind of worked though. I have not attempted to uninstall and reinstall DX at all.

The mobo BIOS was updated last Thursday to F6. It may be possible it was corrupted during installation. Is it worth reupgrading to F6?

MERGED QUESTION
Question from pikagrue : "CPU causing IRQL_NOT_LESS_OR_EQUAL BSODs during boot, W10 installation, etc"

Continuation of this thread
System specs:

* Intel Core I7 6700k Skylake
* MSI Z170A Gaming M5 motherboard
* 16 ram gb
* GTX 980
* EVGA 850w PSU
* Intel 480 GB SSD
* Toshia 1TB HDD
* Razer Chroma mouse
* Corsair k95rgb mechanical keyboard
* Generic asus monitor
* Windows 10 64 bit

Bought a new mobo because I suspected the old mobo was the issue. BSODs still happened. I then traded 6700ks with someone else to test. After trading, my computer ran perfectly fine, and their computer starting BSODing. This makes it nearly 100% that the fault is on the CPU. Are there any reasons why the CPU would cause it? I've already done a full reformat and reinstall of W10.
