What if System Restore doesn't fix the problem?

If System Restore doesn't fix the problem, you can undo the restore operation or try choosing a different restore point. If System Restore doesn't display any restore points to choose from, make sure you have system protection turned on and that you have at least 300 MB of free space left on your hard disk if it is 500 MB or larger, or have at least 50 MB of free space if your hard disk is smaller than 300 MB. If System Restore doesn't fix the problem, you can also try an advanced recovery method. For more information, see Choosing an advanced recovery method.
