Eureeka! Finally a question I know something about! Compatibility mode resets all the settings to the barest basic functionality. That way you can turn them back on one at a time until you find the setting that caused the crash. In your case, it was the power, so you just have to go to options and set them back to whatever settings you had. Because of a bad graphics card, I have to work in compatibility mode so I know what you mean about the display. It's like flying blind! I hope this helps.
