So, I bought a GTX 560 ti from EVGA 6 months ago, it was working really well until taday. I was playing nfs pro street when suddenly my pc shutdown. I tried many things and I found out it was the gpu which was causing trouble. I removed it from my system and my pc worked fine......but as soon as I plugged 560 ti in it it would not want to start...the whole system. The question is, when I removed the 2x6pin connectors the card started as well as the system, obviously there was no display. I don't understand the problem with gpu (GTX 560ti), now I am using my old 9500GT and everything is working as it should. So I want to ask, why is my gpu not working? Does it short circuits when I plug the connectors, or what? Sorry for the long post. Your replies will be much appreciated.
