This is just a guess. Try this. Unplug the computer and leave it unplugged for about 60 seconds. Plug it back in. Push the power switch. If the power switch lights up and the computer does the same thing it has been doing, press the power button and keep it pressed until the computer appears to shut off. Once it shuts off, push the power button once more to turn it back on and see if this makes a difference.
Let us know what happens either way.

MMD, this sounds like a power supply unit (PSU) problem. There is enough power for the led's to light up, but not enough to boot the computer. I recently had a similar situation with my computer (not a HP). I replaced the PSU and it is working great.
Here is a link about testing your PSU:
At the bottom of the page in the link, there is also a video on replacing the PSU.
