Is this a recent problem? If so, use System Restore to fix it. If not
then try this:
- Reboot the machine in Safe Mode
- Click Start / Run / cmd {OK}
- Type this command ***verbatim***:
%SystemRoot%\System32\edit.com {Enter}
Report exactly what happens.

By the way, MS-DOS is a legacy operating system that was
introduced some 30 years ago. It is rarely used these days and
it does not exist under Windows XP. The black screen you're
thinking of is probably the Command Prompt.
