I meant to shut down my desktop computer (Dell Vostro 200) but I think I put it into sleep mode instead. When I came to start it up it restarted on the third try and from the audio and lights I could see that computer is on but the monitor will not display and goes into power save mode instead so I can´t see anything. I have connected the monitor to my notebook and it works so I know it is not a problem with the monitor. I have connected another monitor to the desktop but it does the same things and goes into power saving mode. How do I fix this? I am running on a Microsoft Vista operating system. Any help would be greatly appreciated.
