Is there not a new hardware indicator icon in your system tray ? Or in device manager, is it not listed under unknown devices? (I'm not even sure if XP has unknown devices in device manager though !)

When your PC first boots up, does it list what devices are in your PCI slots ? You'll have to be quick to catch it as its only on for about a second - press the pause / break key to keep it on the screen. If it does, is it listed in there ?
