Not sure if this resolves your issue or not, but on the Signal Out of Range issue, that message appears when there's a wrong refresh rate for the screen resolution you're using.
To fix this, boot your computer up in safe mode with VGA (I think that is the correct option). Once the computer is finished booting up, go to your desktop screen and right-click on an unused part of the desktop and click properties. Next, go to settings and set the resolution to a mode supported by your monitor. If not sure which one to choose, try 60Hz.
