I just bought an msi r9 290x, and when I install it, my computer will turn on, and all the fans spin, but I get no signal on my monitor. I already know its not my monitor or the pci slot, because my computer works with my old card. I know its not the card or my psu, because the card worked in another computer with my psu. Also its not the monitor or hdmi cable because it works with my old card. Also know its not the hdmi port on the new card, because it worked using hdmi on another computer. Also I deleted all of my old cards drivers. Think it might have something to do with my motherboard or cpu. I would really appreciate some help if anyone knows whats wrong.
