Did the card work before? Give us a little more info on your system.
Previously was working once I was able to boot into windows. However since changing everything (moved to ASUS Sabertooth Z77 and Intel i73770k). I can't seem to get into windows. However I was able to remote in so I think the cards just fried and probably not worth the time to try and fix.
Sadly it seems the GF threw out my box with PN and SN and Receipt so I can't RMA. Just going to go spend some and get a 660 TI and call it a day.
