When you roll back two or more device drivers by using the Roll Back Driver feature of Device Manager, your Microsoft Windows XP Service Pack 2 (SP2)-based computer may repeatedly restart, may generate various errors depending on the drivers that you rolled back, or may do both.
This problem occurs when the device drivers that you rolled back use some of the same system files. In this scenario, mismatched driver or miniport file versions may exist. Therefore, you may not be able to start Windows XP SP2 without any errors.
To resolve this problem, use one of the following methods, install device drivers in Safe Mode, or use System Restore to restore the operation of Windows XP SP2.
