Resetting the Computer

You can reset the computer to load a different operating system or to reload the current operating system. For example, if an error occurs and the computer does not respond to your keyboard commands, you can reset the computer and try the same operation again. However, resetting erases all data in the computer’s temporary memory (RAM), so reset your computer only as a last resort.

In MS-DOS, you can hold down Ctrl and press C to stop a program’s operation and return to the MS-DOS command prompt. If an error occurs, try this method before you reset the computer.

WARNING: Do not reset the computer to exit a program unless you have to. Some application programs classify and store new data whenever you exit the program prop- erly. If you reset the computer while such a program is running, you may lose data.
