You probably forgot to connect your hard drive to the new power supply. Make sure it's fully seated.
Sorry, there was a problem. Please try again later.You forgot to plug in the 4 pin CPU power connector to the motherboard (some PCs even have 2 - 4pin CPU power connectors). Check all power connections and power on again.

Now try to boot, if it boots then you can connect the rest of the power connectors after shutting down and unplugging the system. If not you may need professional help.
Sorry, there was a problem. Please try again later.Most likely...the power cable to the HD is either installed backwards or not seated all the way. Make sure you have it installed correctly. I suggest you unplug the HD power cord (of course, disconnect the power supply altogether from the wall first), and re-seat it. Other possibility is that the motherboard power supply cable isn't seated all the way. Check both of those. Good luck!
Sorry, there was a problem. Please try again later.I would recommend bringing your HP Pavilion into a local store's Geek Squad, so they can take a look, and if necessary, ship off for service repair. It sounds like your computer needs service.
