If you remove the memory chips and the beeps are the same. you have bad memory(you can try 1 chip at a time)if the beeps are now different you might review the following codes list

Dell beep codes are available on their support site
2 beeps means memory problems
take out memory and refit ensuring good connect
contacts must be clean, rub gentle with soft pencil rubber if unsure

dear

3beeps almost means cpu failure

you can try to reflashing bios if not you must replace cpu itself
