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.
