Since they frequently display no error message, it can be very difficult to track down the source of the problem, especially if the times they occur and the actions taking place right before the CTD do not appear to have any pattern or common ground.Ī CTD can happen in games of The Sims series for multiple reasons: The CTD bugs are considered particularly problematic for users. Other times it may appear to be triggered by a certain action, such as loading an area. Also during normal function, the game may become a black screen and play the last few seconds of sound (depending on the size of the data buffer) that was being played repeatedly before it crashes to desktop. During normal function, the game may freeze for a shorter period of time, and then close by itself. Many times there is no apparent action that causes a CTD. Usually, the term is applied only to crashes where no error is displayed, hence all the user sees as a result of the crash is the desktop. For crashes that can occur in The Sims games itself, see Game crash.Ī Crash To Desktop (or CTD) is a computer program crash which is said to occur when a program (especially a video game) unexpectedly quits, abruptly taking the user back to the desktop.
