Having problems with your Dell Dimension 2400 PC Desktop ?

Getting my dell motherboards to start up.......

\015 I Removed a DHM Motherboard from a working Dell, placed it inside an identical DHM case and it did not work properly. I mean I can hear it power up, but it starts making a repetitive buzzing noise with no monitor display.... I tried this with about four different DHM cases, still the same occurrence. Is there a secret function that activates or deactivates the cases or motherboards. I'm totally confused because while I have an active Dell DHM, I placed the( so called motherboard that didn't work) inside it and it works perfectly... S.O.S\015

To put it back to that particular spot where it starts to charge is the most difficult and the comp tends to run out of battery ever so often.
