Re: Optiplex 745 no signal to monitor
Orange circle? Power light on front panel?
I would suspect either the power supply or motherboard. However, considering the age of this PC (2005 era) its not worth putting any money into. You can buy a newer/refurbished OptiPlex that even comes with Windows 10 for around $200.
