If you happen to run into problems with a driver, Windows XP has a feature to roll back to a previous version
1. Click Start-->click Control Panel--> Performance and Maintenance.
2. Click "See basic information about your computer".
3. System Properties dialog box-->Hardware tab.
4. Click Device Manager.
5. In the Device Manager console-->right-click the device whose driver you want to rollback-->then click
Properties.
6. If the device is not working, it will likely appear with a red X or a yellow question mark.
7. Click the Driver tab-->then click Roll Back Driver.
Do take note that once you replace your driver ,the previous one that you have just replaced,will no longer be in existence.
