I changed the monitor and cable but still nothing. I turn on the computer and get a green light and I can hear movement but no beeps. What do you suggest?
Sounds like your computer is setting the video to a stand by mode. What happens when you first start up? Have you tried booting into Windows Safe mode by tapping F8 at start up?
I think that message is coming from the monitor and not the computer. The green power LED doesn't mean the computer is working. It only means the LED is getting power. The problem is with the computer. Did anything happen to it between the last time it worked OK and the first time it didn't? When governments outlaw guns only outlaw governments will have guns
