I recently bought a new radeon x1650pro video card and i've been using it for about 2 days with no problem. I was trying to reinstall windows xp and the setup gave me a whole bunch of errors so i quit the installation half way. When i booted the computer my video card wasn't detected anymore. I took out and reinserted the video card twice so that isn't the problem. I also uninstalled the drivers and tried to install them back but it gave me the message saying that the video card wasn't detected. My monitor is connected through the video card and it shows a screen.
