280x crossfire random black screens

[waso_dude]

As title.

Since I have gone back to crossfire on my 280x, I've been getting random black screens - its a bit like if a driver crashs and then Windows 8 reloads the driver.

But I get no error/message saying it has. It onyl happens with crossfire enabled.

I'm running latest drivers. And it appears to happen in all games - only tested in Dota 2 and WoW.

anyone else had this?

Tested each cards individually?

Yea both are fine.

I got a 850watt gold Seasonic PSU so thats over the odds on it too.

Hmm, weird. Have you tried both lanes of the mobo individually? One of the lanes may be screwed

That is something I need/should test actually. I'm pretty sure both are fine.
