[SOLVED] Is this a motherboard issue?

[Tinreo]

This morning, I get up and use my computer with no problems. Later, I leave and come back to find my monitor displaying “DisplayPort no signal”. My monitor is a ASUS VG248QE and the no signal problem is common and the usual solution is to unplug the monitor’s power cable and plug it back in. I do that and it still does not work so I try HDMI. Nothing. Then I try to use the HDMI port on my motherboard. Nothing. Finally, I try another monitor that I had lying around. Nothing for both HDMI and DisplayPort. Also, when I try to turn off my computer by pressing the power button on my case, nothing happens, but the fan controller works.

I turned my computer off and back on by using the power supply’s power switch and it started working again.
