I am currently running a Sapphire R9 290 Vapor-X with a Corsair AX850 Power supply. Frequently the display on both of my monitors will blank out forcing me to hard shutdown my computer. When the display cuts out, from the convenience of Sapphires 290, the led changes colors to show that it is getting hot and all 3 fans start up. I am running the latest 14.7 Beta drivers on Windows 8.1
Edit: Forgot to add that this happens at the desktop, and sometimes after restarting, within 5 minutes of logging in, it happens again.
