hi,sometimes it not a issue with the monitor ,but an issue with the computer ,maybe the video device in the pc is not working ,maybe the computer itself is not working ,like windows is not even starting up when you turn it on ,many ways to troubleshoot this ,first one is try another monitor ,i know not all of us have 2 of them but a lot do ,
does it make windows bootup sound when you turn it on ,can you hear fans running ,harddrive spinning .things like that
