5.The problem could be caused by your keyboard. See “Keyboard Problems,” below.

If your keyboard is operating properly, proceed to the next step.

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

7.If your computer still does not respond, you can reset it using the CTRL ALT DEL command. If that command doesn’t work you can reset the computer with the RESET button. See “Resetting Your Computer” in Chapter 3 for more information.

8.If resetting the computer does not work, turn off the computer and wait at least five seconds. If you do not have a hard disk drive, insert the Startup diskette in drive A. Then turn on the computer. It should load MS-DOS.

9.If you installed a non-EGA or non-VGA display adapter card in your computer, and you want to use that adapter as your primary display adapter, you need to change the setting of jumper J6 on the main system board to disable the built- in VGA adapter. If you have not set the jumper, you will not see any display on the screen.
