If some Windows functions aren't working, Windows is crashing or there are unexplained performance issues, the cause may be that the core system files are corrupted. The Deployment Imaging Service and Management (DISM) tool along with System File Checker (SFC) are 2 tools that can be used to scan Windows and repair the operating system.The first and most crucial step is to check the hard drive to make sure it is not failing.
