Hellow fellow OCUK'rs,
Hmmm so where do I begin?
Firstly, just to advise, I have had issues with my GPU's in the past in regards to clock speeds no sticking etc... But this is far worse than any issues I have faced before.
I'll start from what I think caused it, well I have two Gigabyte 270x's, and I have BIOS flashed them before to MSI for example but always reverted to stock, and everything worked as expected. However, recently I had a go at unlocking the voltage on one of the cards for more overclocking headroom, but it came to nada.
Upon the first restart of the modified GPU BIOS, the actual system BIOS stated the card was not UEFI, and the cards fans where not running, which meant and there was no output to either screen. Now from there, everything has gone pear shaped.
So I went about trying to make the first flashed GPU to work again, every time I booted into windows, after a couple of minutes the system would crash on a grey screen... So in the end I swapped the bottom GPU to the top slot, which then enabled me to re-flash the flashed GPU back to my backed up BIOS (Stock). Now when the system is restarted, both GPU's fired up, and are both detected as UEFI, great!
But now, and it is driving me crazy, because before my system was pretty much on 24/7 and had no crashes, and ran F@H a lot of the time when I was not using the system. I appear to get random white/grey screen crashing. It doe not leaves any trace of a BSOD, or any bug check code of any kind, the system just freezes and the only way around it is a hard reset.
Now what doesn't make sense to me is, I can play Watchdogs and the FPS is fine, temps are good, but then it will crash to the grey/white screen.
However, the same happens on the desktop when the system is pretty much idle with just a web browser open.
I have re-installed the 14.9.1 drivers (Removed them with DDU) and also tried the 14.9 WHQL drivers to no avail.
I really can't understand what the problem is, the system passes RAM tests, the PSU is fine aswell.
These are the things I have tried so far:
What are my options in regards to this?
It really couldn't of picked a worse time to act up as I have no other system to do work on, and I have all my bloomin NVQ work to do.
The system specifications are as follows:
Sorry about the wall of text, if you need any more information please ask.
I really hope to get this sorted soonish to be honest.
Thanks for any help in advance.

These are the things I have tried so far:
- Changed the GPU's around.
- Completely disabled any type of overclcok of the system (Everything is stock)
- Tried testing the RAM (MEMTEST)
- Re-installed drivers (Twice)
What are my options in regards to this?

The system specifications are as follows:
- i5 4670k @stock
- 1600mhz RAM (2400mhz XMP disabled)
- Corsair RM 750
- MSI Z97 Gaming 7 (Latest BIOS)
- H100i
- 120GB SSD (Kingston)
- 2x Gigabyte 270x
