hi, i'm running a fx8350 with 2 7850 2g in xfire. my mobo is a gigabyte ga-990fxa-ud3. at times i'm getting a 2-3 second black screen. my sound is still working. i'm using the current 13.12 driver. it occurred on my 23 inch hp monitor and now on a 27 in aoc monitor. i tried reloading the driver and that worked for the night but the problem has returned. i've played with the settings in catalyst menu. it started about a couple of months ago. i've changed my gpu clock speed and memory clock settings. it has been set to max and to default and the problem persist. i can be in game (bf4) or just using my browser, it happened when i was typing this thread. i'm using a hdmi cable from the top card to the monitor. anyone have this issue or know what it is? its driving me crazy when i'm in game.
