Series of long beeps Dell Precision 350

[dbrown]

Hi,
i have to re-build a workstation for a returning employee
i took an older PC tower (Dell Precision 350) and plugged the tower in to see if it still works but i heard a serious of long beeps with a number sequences of 5-1-2-3.
i have been trying to research the beep sequence but no luck
if there is anyone who can give me a hand it will be great thanks
