nonbootable floppy disk or CD. Insert a bootable floppy disk or CD.
NON-SYSTEM DISK ERROR — There is a floppy disk in the floppy drive.

video cable connectors have missing pins, but not bent pins). Ensure that the
video cable is connected as shown on the START HERE sheet for your computer.
PRESS THE MONITOR POWER BUTTON — Be sure that you firmly pressed
the monitor power button.
CHECK THE POWER LIGHT — When the power light is lit or blinking, the
monitor has power. If the power light is blinking, press a key on the keyboard or
move the mouse.
TEST THE ELECTRICAL OUTLET — Ensure that the electrical outlet is
working by testing it with another device, such as a lamp.
SWAP THE COMPUTER AND MONITOR POWER CABLES — Swap the
computer and monitor power cables to determine if the power cable is defective.
TEST THE VIDEO EXTENSION CABLE (IF USED)—If you are using a
video extension cable and removing the cable solves the problem, the cable is
defective.
TEST THE MONITOR — If another monitor is available, connect it to the
computer.
