If your computer locks up and does not respond when you type on the keyboard, follow these steps:

1.Some computer operations take longer than others to complete. For example, the computer takes longer to sort a database than to accept a single typed character. If your computer is still locked after a reasonable length of time, proceed to the next step.

2.If you are running an application program, check the section below called “Software Problems.” This section covers certain problems caused by application programs.

3.If you want to stop whatever the computer is doing and return to the MS-DOS command prompt, hold the Ctrl key down and press Break. In most cases; this solves the problem. See Chapter 2 for more information on stopping a command or program.
