Help please!!! Last night i went to upgrade my Dell Dimension 8200 video card with a GeCube ATI Radeon X1650 512mb DDR2 video card with no success. First I removed the old video driver for the orginal nvidia card. Shut the computer down removed the original video card and then instlled the new card. When I went to boot up the computer it would not fully boot and the monitor recieved no signal. I reseated the card a few times and still no boot or video feed coming through. I then proceeded to put the old video card back in and still no boot or video signal. All that turns on are the fans and the cd roms. My final attempt to make sure my computer was not toast I started it with no video card in the slot and it booted right up from what i can hear since i dont have any video / monitor hooked up. It goes through its usual sounds and boots up fine. Any thoughts? Thanks!
