You need to say exactly what the circumstances and what happened during power failure and exactly what happening when you power up now. Take the side panel off and look inside when you power up. Do the fans spin ? You should disconnect everything and reconnect only the mouse k/b and monitor. Also turn off your PSU using switch on it (if present) and unplug from the mains, and try again after a bit (say, 8 hours). Which lights come on the front panel ? Power ? Hard disk activity ? Does it try the CD/DVD/floppy ?
There used to be (it might till be there somewhere) a page describing the what the behavior of the lights on the PSU meant.
Short of anything visibly obvious inside the case and no other symptoms (as you describe) I'd try swapping the PSU for a known good one but it really might be almost anything. Your HD might have been caught in the middle of doing something making that faulty. Fault finding is mostly educated guesswork then random chance. Maybe in the worst case your m/b is dead.
A lot of HP Pavilion laptops suffered from improperly installed VGA chips on the motherboard which did not have properly thermal control. Overtime the chip will partially or entirely lose contact from the motherboard and you will experience this symptom.
This started with early 2007ish Pavilion DV2000, 6000, and 9000 series laptops, but has been an ongoing issue in several models since. A repair is possible, but NOT by baking your motherboard or using a thermal heatgun.
You need to take it to a lab with an infrared REFLOW machine to properly REFLOW the solder from the VGA chip to the motherboard. Going rates are from $75 to $150 flat for the job.
Actually it boots, just that you don't see it. Try using another monitor - even a tv will do: disconnect the present monitor, connect the new one and reboot. If you get an image then the monitor is dead, replace it. If you don't then the onboard video card id dead, get a new one and try again. If even now it.s dead then you need a new motherboard.
Sounds like the pc power supply is bad... U can replace it, but if supply went out it may have damaged the motherboard. In future, have monitor blank off automaticlly and install UPS to supply pc. HP has histroy of weak power supplies.
