Powercolor PCS+ R9 290, 18 Months old.
I have never had any Black Screen issues with this card in the past, over the last 6 to 8 weeks its become a problem.
What's happening is the screen will go black and then into standby, the computer is also frozen and i have to hard reset, alarmingly sometimes i get a Motherboard error beep and a GPU error light. when that happens it will keep doing it until i physically remove the GPU and put it back, after than it will start again and run fine.
It Black screens like this in Cryengine's Sand Box Editor (EaaS 3.8.1) it will also do it just browsing the net or Youtube, but it seems to be that volatile only after its had its black screen crash, letf turned off for a few hours it seems fine until i use Cryengine again. its done it once in world of Warships, never in BF4, Mantle
Any ideas whats wrong?
