hello there, look like your power supply is bad, check the cables inside you desktop if all are connected from the power supply, if it the same, replace your power supply, you can check this:

Only issue is that it uses an external power supply, using one of HP's laptop adapters.

ok, you will need to open the case on your desktop and check the power supply inside your desktop and cables make sure everything is connected,it will look like a square box inside the desktop.

Hello,

4 beeps is usually issue with power. Make sure you are using the right adaptor too. This unit uses a 180W or a 135W adaptor. If you use a lower Wattage adaptor (that of a laptop), it will beep 4 times.
