Detecting hardware and installing drivers in Windows XP

Try Driver Identifier. I just reinstalled XP on a 6 year old Presario laptop and got most of the drivers from the HP site but still had a few in the device manager. DriverIdentifier will scan your hardware using a unique method. It will indicate the name of the manufacturer and version of your devices. DriverIdentifier has a huge database of drivers from all hardware manufacturers. It will give you the most updated drivers for your machine.
