Once Windows is in Safe Mode, you can actually perform whatever problem solving steps that might need to be done.
If you can access Windows normally, you also have the option of configuring Windows to start in Safe Mode automatically the next time your computer starts. See How To Enter Safe Mode Using the System Configuration Utility for instructions on doing this.
