- I have two R9 290 Saphire cards in Crossfire.

- After an extended period of time having these cards running the screens will suddenly go blank.

- The issue occurs if I am running one, two or three monitors.

- It usually takes 1-3 days before something happens. I can be playing a game and suddenly everything goes black or I can leave my computer alone for a while when I come back it is blank. If it happens while I'm at my computer the graphics card fans run at normal speed and I restart the machine. However, each time I have left the computer alone and the issue occurs the graphics cards are both running the fans @ 100% non-stop. I check for heat but the cards seem to be quite cool in temperature. So I hard restart the machine and it is fine.

- I am running stock standard refresh rates on all of the monitors being Viewsonic V3D231, QNIX QX2710 Evo II, Benq XL2411T. I do overclock these but for testing they have been left @60hz refresh.

- The monitors appear to still be receiving a video signal because they do not show they have become disconnected (ie no signal message).

- The computer remains turned on and appears to be running but I am unable to shut it down gracefully using the power button.

-There is also no sound coming from the computer if a program was outputting sound, so it seems all processes have stopped working completely.

- This issue only occurs when there are two graphics cards in the machine. I can take one graphics card out and there is no problem and the computer will run forever without a problem. I have tried each card indiviually and there appears to be no fault with either in a single hardware configuration.

- The cards to not appear to be overheating and I am not overclocking any component in my system. The fans run on auto and do not tend need to run more at than 20-30%. I have checked system temperatures and they appear nominal.

- When I restart my system the problem will often occur again within a much shorter time span - indicating a potential issue with overheating - however as I said my system does not seem to be overloaded and appears to run cool. Neither should it be an issue with power supply as I have a 1000W corsair which should be more than ample. A calculator for power shows I only require a 650W power supply to run this machine.

- Maybe a ram issue? I have had issue with the ram and boosted the voltage up to 1.75v and it has run stable. It was unstable at 1.65v. When the ram failed the machine locked and the screens were still showing video output which indicates a different fault not related to the graphics cards.

- All my tests have been performed with the cards in crossfire and with crossfire turned off (with both cards still enabled). I recall the same issue occurs either way.

- Is it a possible issue with clock speeds / timings / motherboard configuration?

- Different Catalyst drivers have been tested. Mobo upgraded with latest firmware. Windows 8.1 fully up to date. Even tried reinstalling.

Here are my system specs. Any help is greatly appreciated. Dxdiag is in a txt file here :
