My monitor has been behaving very strange so I'll explain the best I can. Hope it makes sense lol. I have a custom built computer that was a graduation gift so I don't know exactly what the hardware specs are, but the monitor is a Dell. I've had it for a year and a half and it's always been fine. Last week, I turned it on and the monitor wouldn't come on. The computer was running and making all the noises it does when it starts up, but the monitor wouldn't display anything. The monitor light would be green for a couple of seconds then go back to amber. It's like the computer isn't talking to the monitor. I've tried everything, reseating stuff inside the case, reattaching cables, and I hooked the computer to another monitor to see if it was the video card. It worked fine with that monitor. All my monitor has is a colored box that bounces around on the screen saying either digital or analog depending on which button I press on the screen. Here's the weird thing. After I took the computer back from testing it with the other monitor, it worked fine with mine. I thought it was just a freak event and didn't worry about it. It was fine for a couple of days because I never turned it off. Well, I turned it off for the night and the next morning, the same thing was happening. I've already had some friends who are usually pretty good with computers look at it and they're stumped and I'm out of ideas so I'd love some help. Thanks!
