Did you try the old reset?

Unplug the power, if a laptop remove the battery. Press and hold the power button for 60 seconds, release, apply power and try again.

http://h10025.www1.hp.com/ewfrf/wc/manualCategory?cc=us&lc=en&dlc=en&document=&product=3856275 has the manuals but HP does not issue repair manuals as not everyone repairs PCs.

You can use google and Troubleshooting The Dead PC to see what others do but the symptoms are not telling me it's anything specific.

Since this is a desktop PC, then having the "green LED lit" on the AC area is only telling you AC power is present, NOT that PC operating DC voltages are up and running, one or all. Next, if the PC beeps other than what it normally does, refer the bios beep code in the manual or for that model# PC. Also, take side cover off and check the status of the innards when power is applied. If the fans move a bit then nothing that suggests improper PC voltages or unstable. In most cases, the best fix is to try another PSU rated the same or similar(larger). If you have one around, simply unplug yours and then connect the spare in its place though it need not be inside the PC(testing only) and check results. Physically "jerry-jig" it for now. If you have a physically similar, then replace PSU entirely and mount in its place and then test. If it fails, then you probably a bad mtrbd., now you have your excuse either to order some used mtrbd. via eBay or Craigslist or buy that new PC. I suggest you also have a decent surge protector and/or UPS setup too to protect the PC when running.

I hope this isn't you but check out posts here:

Oh no Willie, that's not me in the link but I did try those steps from HP already. None of that seemed to help. I would hate to buy another PSU or mobo though and just keep trying the extra parts. I'm no advanced tech or anything. It was plugged into a surge protector and all the other stuff (i.e. modem, tv..) came back on when the power did. Only the computer didn't. I thought surge protectors protected computers and stuff from these power outages.

Surge protectors

FYI- While providing some protection against electrical overloads or "surges/spikes" on the AC line they also provide fire protection. The arcing and sparking that could result if an "open circuit" doesn't happen which basic protection provides up to a certain point(rating) and/or becomes grounded(re-routed). On top of all this, it may provide that only ONCE! as the protection has been used up or defeated and if still running is at typical basic AC operation, thus "unprotected" mode. All depends on the grade or level of surge protection and/or degree of what's provided besides surge protection.

Since a PC runs at 5v and 12V, anything above that is bound to cause issues. So, even a 50V spike or 50,000V hit should produce negative results. What this boils down to, is the end result, of all devices protected, there is no fire, devices get saved and/or more are up and running after a spike or hit. PCs are weak links as it doesn't take much to bring it down. Take my advice an get another surge protector and look for better joule rating. On top of that, use singular surge protector to attached at AC cord/or wall themselves even before the strip type protector.

I'm betting its a fried PSU

I had the same problem w/ a Dell after an outage. And like you, I'm no expert but don't try to figure things out and fix myself. It just takes twice as long as someone more knowledgeable. Researched the problem on my laptop. Most answers suggested it was the mb, but I opted for the cheapest solution first which was the PSU. Bought and after-market PSU at Staples for around $40 bucks, installed it and my computer was up and running again. The outage fried the PSU even though it's allegedly protected by a very expensive surge protector.
