Think 2 GPU's just died on me, they were only young as well!

2 of my 570s seem to have died on me, changed over the risers just incase, but still cause a hard crash when I try put them to use. They were only 3 months old as well, admittedly they have been running at 100% for that time, but even still expected a little longer from them.

Time to arrange an RMA I suppose, will investigate further tomorrow and test each card separately before I make the phone call.
