I have never come across one that did yet. I did wonder if it was on standby and not shut down. The other explaination is that since ATX PSU's came along they do have a constant 5v supply to the motherboard. It is used for switching the PC on as well as wake on lan and other wake up PC functions like serial and mouse, keyboard etc. So maybe it was bleeping for something - maybe just to remind you it was on standby.
