The problem is the power supply it will need to be replaced.

Go to HP Support & Drivers 1

try removing all power cables of your computer that are connected to the surge protector. reset the surge protector. wait for about 5 minuets before you turn on the surge protector. then plug all cables that your remove from your computer the turn on the computer.

Try replacing the power supply, a blinking green light usually means the power supply is missing an output voltage. If you do that and you still get a blinking green light then the motherboard will need to be replaced.

As always verify all cords are plugged in properly. After that it sounds like you power supply went out. It is not that hard to replace. Make sure you unplug power cord. After you remove the pc cover, Usually you just need to unscrew 4 screws for the power supply. Somewhere on the power supply it should say how much watts it is. Anywhere from 200 watts and up. Just replace with exact wattage.

Remove your main power cable on the back of your PC. Let it sit idle for an hour and then try and power it up again. The memory in the BIOS should clear up and power back on.

If the component with the blinking green light is on your network card, it has nothing to do with your problem, but does demonstrate that *********** board is NOT fried or there would be no voltage available to make the light blink.

Something on your board may be fried, but not the entire board.

Unit needs board level service, so obtain an RMA, if available and submit the unit for bench testing and service.
