Yes, I've plugged in the video card in both pci slots and neither one was able to create a display on my monitor.
What I mean by not recognize is that the computer screen is completely black. It won't show anything boot up on the screen. The computer completely powers on, and I hear everything else running. Even the video card fan is running. I also put back my old video card and then everything was running. I then even removed the drivers of my previous video card and then reinstalled the HD 5570 but still nothing shows up. If you need anymore details, please let me know.
I have securely seated it in the slot, but there is no pci-e cable. The XFX radeon HD 5570, doesn't have the power slot.
