Please go to Start -> Run -> cmd and press Enter. At the command prompt type sfc /scannow, making sure to put a space between the "c" and the slash, and then press Enter. This will run the System File Checker. Follow the prompts, and insert your Windows installation CD if requested. Then please restart your computer.
