RE: optiplex wont display

The orange LED on motherboard is normal.

What color is the power button and is it steady or blinking?

Have you checked the pattern of the 4 diagnostic LEDs on the front panel. If any of them are still on after the PC boots, look up the error code in the manual, page 66.

Have you checked the connection between PC and monitor at both ends? Can you test this monitor and video cable on a different PC, or a different monitor and cable on this PC?

If memory is bad it will not display anything.  The diagnostic LED's will also 1 3  display ram as bad.  If processor is bad the power button will be solid amber.
