Hi,
Welcome to Microsoft Windows 7 Answers Forum!
To troubleshoot this problem you can follow the steps provided below.
Try performing SFC scan on the computer.
1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are
prompted for an administrator password or for a confirmation, type the password, or click Allow
2. Type the following command, and then press ENTER: sfc /scannow
[The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.]
A message will appear stating that 'The system scan will begin'. Be patient because the scan may take some time
3. If any files require a replace SFC will replace them. You may be asked to insert your
Win7 DVD for this process to continue
4. If everything is okay you should, after the scan, see the following message "Windows
resource protection did not find any integrity violations"
5. After the scan has completed, close the command prompt window, restart the
computer and check.
