Desktop off
My Dell Desktop Inspiron 2350 automatically shuts down after a few minutes. It doesn't go to the shut down phase, but instead just turns off (screen goes blank and shuts down). I hear the fan running, and i cleaned out any dust that might have accumulated, but it states "CPU fan not detected." How can I rectify this situation? Thank you.

The first step would be to confirm that the fan is actually running. Physically look at the fan to make sure it is on and stays running. It is also possible the fan is defective and the MB is not receiving the signal confirming the fan operation. This forum post may help as well as this Dell support page.
