My Desktop has been experiencing this issue for several years now. When I shut down my computer or go through the restart process the signal to the monitor is lost and will not come back.
I see the "Shutting down" blue screen and when it flips to restart, the display disappears. The computer still hums away and restarts (I believe) but the display does not return. I've tried several different monitors, video cards and connections (HDMI, VGA, DVI) even on the motherboard video slot.
I have found that by :
1: Holding the power button to hard shutdown the computer.
2: Pulling the power cord and removing the CMOS battery
3: Wait 10 seconds to clear then replace and restart the computer
This clears the issue and the display comes back up right away. I don't know why, but it always does. However, the problem happens every time I try to restart.
Can anyone help or has an idea?
