Hi Mano999,
A. When exactly are you getting this error?
B. From when are you facing this issue?
C. Any recent changes made on your computer?
Method 1
Run a System File Checker which scans for and attempts to fix corrupted System files.
- Click on the Start menu, choose All Programs, then Accessories, then right-click on the Command Prompt item and select Run as administrator.
- Click Continue to authorize opening a command prompt with administrative privileges.
- Run this command in the cmd prompt: sfc /scannow
- The cmd prompt should list text stating "Beginning system scan. This process will take some time."
- Wait for the scan to complete (this can take several minutes so be patient). This command will scan all protected system files and attempt to replace incorrect versions with correct Microsoft versions
- When the scan completes, the SFC tool will indicate whether or not it found any problems and whether or not it was able to fix them
- If any errors are reported that SFC was unable to fix, there are steps in this knowledge base article that explain how to locate and attempt to fix the errors.
- After fixing any errors that are found, try to use Windows Vista Media Center again.
Method 2
Boot to safe mode and see if it is better. Safe mode starts Windows with a limited set of files and drivers. Startup programs do not run in safe mode, and only the basic drivers needed to start Windows are installed.
1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
Click the Start button, click the arrow next to the Lock button, and then click Restart.
2. Do one of the following:
· If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you will need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
· If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.
3. On the Advanced Boot Options screen, use the arrow keys to highlight the safe mode option you want, and then press ENTER. For more information about options, see Advanced startup options (including safe mode).
4. Log on to your computer with a user account that has administrator rights.
When your computer is in safe mode, you'll see the words Safe Mode in the corners of the display. To exit safe mode, restart your computer and let Windows start normally.

- Click OK.
