If you are using Windows 7, just type event in the search box and Event Viewer should be one of the search results. Select this, then go to Windows Logs, select the System Log, then filter it for Critical, Error, and Warning events. Look for an item that occurs at relatively the same time as the black screen problem.
It also wouldn't hurt to similarly check the Application log as well.
