I turned my computer on this morning, and after about 20 seconds, the screen turned black, and stayed black. The light on the monitor was still green.
I have to turn the monitor off, and then turn it back on in order to see something through the monitor, but the screen turns to black about 5 seconds after I do that.
I understand that a screen turning black and the monitor's LED being green would greatly point towards a video card problem, but wouldn't the fact that turning the monitor off > on makes the image work for a couple of second mean that my monitor is defective? It is a 7 years old flat-screen...
Of course, I would test with another monitor if I had one, but I don't. So, my question is this: is it likely that the problem lies with my monitor, or is it almost certain that it's a video card issue?
