Hello. I have just finished building a computer, but when I turned it on i noticed that the graphics card fans are not spinning and there is no display. I am using a Gigabyte radeon R9 270 graphics card with a ASUS M5 A97 motherboard. There seems to be power because the card is giving off heat, but i am not getting any output display. I have also tried reseating the graphics card to ensure that it is locked in, and it is. Is there anything else to try before calling it a lost cause? Thank you.
