Sometimes, the installation of a program (or a driver) can cause an unexpected change to your computer or cause Windows to behave unpredictably (errors, system freeze, etc). Usually, uninstalling the program or driver corrects the problem. If this doesn’t help, you can try restoring your computer’s system to an earlier date when everything worked correctly. How can you do that? Using Windows System Restore.
To access Windows System Restore, start by clicking Windows Start button > All Programs > Accessories > System Tools, and then clicking System Restore.
Note: System Restore can undo system changes to your computer without affecting your personal files, such as e‑mail, documents, or photos. However, is not intended for backing up personal files, so it cannot help you recover a personal file that has been deleted or damaged.
