Use System File Checker to scan your PC for missing or corrupt files. To do this, follow these steps:
1). Click Start, and then type cmd in the Search box.
2). In the results area, right-click cmd.exe, and then click Run as administrator. You may be prompted to type the password for an administrator account.
3). Click Continue if you are the administrator or type the administrator password and then, click Continue.
4).At the command prompt, type Sfc /scannow and then press ENTER.
The scan may take some time, so be patient. Windows will repair any corrupted or missing files that are found. If information from the installation CD is needed to repair the problem, you may be prompted to insert your Windows CD.
