There are times I'd call that a video card failure but I have so little machine details, it's just a guess.
My computer froze, was unresponsive, I restarted, the monitor displayed everything fine, I saw and selected "start windows normally", after the "starting windows screen" the monitor displayed "no signal" and went black. I could hear the start-up tune in the speakers and the monitor worked fine up until it started up. I am currently in safe-mode with networking and the monitor works fine. I am not at all computer-savvy so please give me any ideas what might be going on right now. Any and all ideas or suggestions of what I should do are welcome.
