Okay the other day i had a power surge and i had to mess about with my pc so i dont think it is my gpu because i put that in a diffrent pc and got display and also i put a gt430 into the pc with a problem , the pc only has a problem when i have my titan in it not when i have the 430 in it , so i thought my psu might not be outputting enough power anymore so i replaced that and i still get no display , im just lost now , help me please
