Hi, I have an EVGA GTX 980 Ti 6gb graphics card, and the problem is that there is a normal / LN2 switch on the card, if the card is in normal mode, the PC will not turn on and don't POST, it will try to spin the fans, but immediately they stop, it seems to me as if it was still rebooting, but if I switch the card to LN2 mode, the PC turns on normally and the card works normally, the fans are spinning, I want to ask if someone had a similar problem, or does not think what could be with the card ? I remind you that there was no flash vbios on it.
