Re: XPS 8300 4 rapid beeps
Have you tried one memory module in each of the 4 memory slots? or just one slot? I had a PC (not an 8300) in for repair with a memory problem and two out of the four slots were bad.
As the replacement motherboard is, apparently, used it could be defective. The symptoms changed with the replacement motherboard but I would suspect the replacement. If you bought it with a warranty I would contact the seller.
