Hi R-O-G Guys 😃 . Well ive builded a new System basically its Rampage III Extreme , Corsair Dominator 6 Gig , Core i7 920 , Corsair 1200 Watt PSU and 2 x GTX 580´s .
Had the System running for a few days on a benchtable be4 i would be take the parts in the case ( just to test the system ) . Yesterday i putted all in the Case and then suddenly i think 1 of the 2 GTX 580´s dissapeared . The Card starts with 100 % Fan from booting and when i enter Win7 the Card isent reconized by any tool like GPU-Z for example . Ive tried pretty much everything . Tried every PCI-E Slot on the Mobo , everytime the Card spin 100 % and dont give a Signalscreen . On the other Hand the second Card doing it well as she should , everything fine with her . It would be strange if the Card dissapeared already since both of them including the rest of the System is only a few days old and neither of these two was overclocked by me , but they had a tiny factory oc i think . Ive had very much Graphics Cards in my Life but never had a broken one so far . Dont get me wrong i dont wanna claim Asus quality or something here , just wonder if some of you guys may experienced or heard something like that be4 and could give me his conclusion or thaugths .

Regards !
