Question about Acer Aspire m5640 PC Desktop
I assume you are using the integrated video, (on board). With a new power supply and motherboard you have eliminated all but the monitor. Try a different monitor. I have also seen a case where a computer tower worked fine in one setup with a flat screen, but when hooked up to an older CRT monitor it would not display because of the resolution settings.
