I just replaced my old video card in a Dell Dimension 9200 desktop. I've placed the video card tightly in the motherboard and have connected the fan as well on top of the video card.
Now when I turn on my computer (Ubuntu 11.04) at the BIOS screen it asks me to press Ctrl+I to configure. However, when I do this the BIOS configuration comes for about 2 seconds but after that the screen goes blank and I get a message
No Signal input Check Video Cable
What could I be doing wrong here?
