I recently built a computer from scratch – lots of fun. But I have run into a problem with my monitor. Everything was working fine when one day I turned on the computer and the monitor couldn’t find a signal (Samsung model # S24D390HL). This happened frequently. My temporary fix was to unplug the computer, the monitor and the HDMI cable and then plug them back in. The monitor then worked fine. I found what I thought was the problem: updating the graphics card drivers (ASUS GTX660 NVidia card). That seemed to do the trick but then one day I turned on the computer, no signal, unplugged everything, and still nothing. I spoke to Samsung who suggested that maybe Windows (Windows 7 Pro) was updating drivers and got interrupted which corrupted the drivers. They suggested trying a different monitor to get a picture, updating Samsung drivers and then re-connecting my Samsung monitor and then disabling Windows graphics card update. They said it’s better to update directly from NVidia site.
My current dilemma is that I only have another older model monitor with a VGA connector. I tried connecting it to the onboard motherboard (ASUS Z87-Pro) VGA connection. Nothing. Is there a way to disable the graphics card without physically removing it from the motherboard so I can use the onboard VGA connection?
