Hi! You've received dozens of messages akin to this, but I thought maybe you'd be interested in a pickle: EVGA GTX 980 ti stopped working after changing thermal paste. I have checked possibly dislodged components, and nothing seems to have shorted. The PSU fires its failsafe when the card is plugged in, though. If you are interested in having a try with it, I'd gladly arrange a video call some day.
