Check that the AC adapter is plugged in all the way in the back of the PC. If it's not, the PC will not be able to detect the wattage and will state there is an unsupported or unknown PSU attached.
If the power adapter has lower wattage than the PC is expecting, it will just beep at you.
HP have the same connector for a lot of different desktops / laptops. You may have the incorrect adapter connected, even though the plug fits.
Check the wattage on the underside of the adapter. Yours should be 120W. If it's any less than this (90w or 65w) It'll turn on, but just beep loudly.
