- close all applications, save any open files.

- Click on the "start" button, then mark "All programs" then "accessories, system tools and system Restore. From the list select the point created just before the problems started. The program then restarts the computer.
If after rebooting the problem remains, try to pick an earlier restore point. In that case, if the list of restore points does not appear, verify that system Protection is turned on, and the disk has at least 300 MB of free space:

- click "start", choose "control Panel," "System and maintenance" System.

at the left select the command "system Protection".

- enter the administrator password if necessary. Check the box next to the disk and confirm by pressing the OK button.
