|This is a tricky scenario, it happened to me and was a headache...|
When you start up your computer, did you try these things in safe mode? (Go to start>control panel> device manager > display adapter. Uninstall the display adapter and restart the computer. ) Or does the black screen with the "out of range" come on even in safe mode?
If that doesn't work, you MAY have to hook up a monitor that supports the resolution your display adapter was changed to, and change it back...if you have another monitor to use.
