A Dell Dimension 2400 OEM refurbished motherboard with a 90 day warranty can be purchased from here:
Also, from here:
https://www.serversupply.com/products/part_search/pid_find.asp?pid=123278&
And from eBay:
http://www.ebay.com/bhp/dell-dimension-2400-motherboard
You need to remember that these motherboards are the same age [10+-years] as your Dimension 2400, check out the seller's return policies.
Because of age of the 2400, maybe you should consider replacing it with a new model.
