Yesterday while using the computer, I was uninstalling some discretionary software when a pop-up informed me that the computer needed to be reboot to finish the installation. I don't remember what the particular software was that I was uninstalling, but suffice it to say it was not a critical piece of software for the computer. I clicked 'yes' to reboot. While the computer rebooted normally, the monitor remained dark yet I had a mouse arrow. When that would't go away I performed another reboot. This time, the monitor would not come on and even the mouse arrow was gone. The only thing I have displayed is "no input signal". The monitor works fine as I'm using it right now with a laptop. I've tried two other cables (I'm using DVI to HDMI connected to the onboard Intel HD Graphics 4600). I plugged a known working monitor into the computer with the same result... "no input signal". Sound like a motherboard? Give me something else to try. Thanks in advance.
