Hi,

I am using a Dell Dimension 2400, which I have owned for around 4 years. Just yesterday, when booting up my PC, an error message showed up during the booting process (on the MSDOS looking screen). The error message stated that my computer fan was not detected. But when I placed my hand behind my computer on my fan, I felt a reasonable amount of air passing through. It's obvious that my CPU fan is working so is this error something that I should be concerned about, or can I simply ignore it? Thanks!!
 
There are several fans in the computer, what you felt was probably the rear case fan. The only way to tell if the CPU fan is moving is to open up the computer and see if it starts up.
