Why did you put it in this "other pc"? Was the "other pc" broken in anyway (did it kill a video card before)? Is the "other pc" working now with another video card (dedicated one)? Did you took some precautions about static discharges before and during the removal of the card from your pc?
other pc was and is fine, it has a 550ti now. and no precaution was taken , i remove components all the time. i'm pretty sure stat didn't kill my card. cause then i'll be mourning over my 570 and 2500k at same time.
