HP EliteDesk 800 G1 USDT. After connecting the power cord and I pressed the power on button, the system powers on and immediate the fan stops and it gives 5 sets of four beeps with red light flashing on the power button. And nothing happens after that.

most likely power supply related, try disconnection all drives ext devices except for the video/ram and if still getting this error try replacing the pwr supply

 

note that some systems have motherboard connectors for the Drive power instead of on the power supply
