Hello!
 
I have two GTX560 FTW+ cards.  I was running them in SLI but I have lost my SLI bridge.
So since I lost the bridge I put one of the cards back into its box and have been just running one card.
(I plan on buying a bridge from the EVGA store later )
 
The card I am running seems to some times randomly corrupt the screen with a sort of rainbow pattern.
when this happens the PC completely freezes and I have to press the reset button on the front of my case.
 
But its random I can't seem to find a way to replicate the problem at will.
Its happend on the windows welcome screen once. its also happend while switching to full screen on a youtube video.
But sometimes it does not happen, before posting this post I watched a full screen youtube video with no problem.  It seems totally random.  I have tried the other card and these things do not happen.  I have tried the card on more than one PC and get same result.
also happens with a fresh windows install so I don't think it is a driver issue.
 
Should I just contact EVGA support and request a RMA?
 
Thanks for any help!
