Hi Ptrapper65,
Thank you for visiting Windows Vista Forums.
Let us run SFC /scannow to replace any corrupt or missing system files.
This command will immediately initiate the System File Checker to scan all protected files and verify their integrity, replacing any files with which it finds a problem.
1. Click Start
2. Click All Programs
3. Click Accessories and right click on the Command Prompt.
4. Select the Security Tab and choose "Run as Administrator"
5. Click on Command Prompt
Type SFC /Scannow
The System File Checker tool scans system files and replaces incorrect versions of the system files by using the correct versions.
