This could be a bad power supply or a motherboard failure.

Do not buy a replacement power supply. See if you can borrow a genuine HP power supply to test with or ...

Take to a retail store that sells certified HP power supplies. Talk to sales agent if possible

If the power supply (120 watt minimum) works then buy it. If not then there is a serious problem with motherboard.

HP power supply may have a special "pin" and your system may not work with a cheap imitation.
