I bought a Ati Radeon 9200se pci card, installed it and it worked great. My curiousity got the best of me when I plugged in an s-video while everything was on and the screen went black and the it hasnt worked since. When I started it back up all i got was the black screen. after messin with it for a while it seems that the pc wont even acknowledge the card is in its slot. i cant get anything but a black screen when i start the pc with the card in it. the only way my pc works is w/o the card. its rather irritating that i cant get it to work again after having it for so long. help turn my expensive paperwieght back into a video card.
