Hello! Ive just bought an gtx 780 lightning that seems to have stopped to work. I get no signal form the card to my monitor. Ive tested vga, dvi and hdmi cables and none work, ive tested all pcie ports and none works. I did try my old tx 560ti which worked and i did get a signal. I noticed that the led lights above the card did go bananas when i tried to get a signal, i have a video of it here http://www.youtube.com/watch?v=p3ha0AVGfBA the card also sometimes start with 100% fan speed and i have a video of it here http://www.youtube.com/watch?v=4AsHM-uGquQ And i still get no signal. What should i do? Are those leds showing a code or something for the problem?
