Hello there, my GPU stopped working all of sudden and there's no display at all when connected to GPU but the display comes on when I connect to the motherboard. However the fans are spinning at the first 30 seconds and then stops. I connected GT 720 (which has no PSU connector to it) and the display comes on! Could it be my graphics card being dead? Should I RMA it? Please let me know if theres anything else I can do before RMA'ing it. I don't have another PC to test my GPU. I just have a GT 720 to test on my motherboard which works fine.
