My PC crashes and turns off or short circuits when I try to play a game with my 3070 GPU. But I tried swapping in an old 750ti and it works without a problem. Could this be a PSU related problem? I had another PSU that burnt up and took an ssd with it, the new PSU is 80plus gold 850 w but its used. Im wondering if this is a PSU issue or if my 3070 is fried. I got COD Cold WAr to work on all low settings and dlss ultra performance. What do yall think???
