hey everybody I have a question about my computer. I have a Dell Dimension desktop and was wondering, is it better to completely "shut down" your computer when you are done with it or is is okay to leave it in "standby" mode??? The reason I am wondering is that even in "standby" mode the little fan in the back of the tower constantly runs. Is it supposed to do that?? and what is the purpouse of the little fan anyway??? Thanks in advance Wanna kill these ads? We can help!
