When ever I unplug my PC it takes sometimes 20 tries or hundreds of attempts to power on. Sometimes nothing happens when I press the button, sometimes a revolution or two of the fans then immediate loss of power. But once I get it running it's one press starts without fail until it is unplugged again. When running there is no other issues that are apparent. I have a brand new power supply, hoping it would remedy as well as a new video card and power switch.
