Possibly the motherboard, although you are in the wrong forum.
Unplug everything > Take the side off > There will be green RAM chips (Google if you don't know what these look like), press the white tabs on either side of them to pop them out > There will also be a battery similar to a nickel-sized watch battery, take it out and put it back in > Plug PC in > turn it on... Does it beep? If yes, that means your motherboard is probably OK. If no, your motherboard is possibly toast. > Either way, Put the RAM back in > Try powering on again... If nothing else, try contacting HP chat support to see if they can walk you through some computer-specific things.

First perform a power drain -
Disconnect everything from your computer and then hold the power button down for about ten seconds.
Flip the red voltage selector on the back of the power supply from one side to the other so it is set appropriately for your region (usually 115v in the US)
Plug the monitor and power cord directly into a known good power outlet.
If problem remains take try using the power cord from the monitor on the computer.
If the green light on the power supply is lit up then disconnect everything and hold the power button down again, then open up the case and reseat the main power connector which has about 20 red, black, and white wires coming out of it and a white plastic connector on the end. If there is a four wire connector with black, white and yellow wires coming from it then reseat that as well.
You will also want to reseat the wire that goes from the power switch on the front of the case to the motherboard. it is usually a thin green and white wire.
Still not working? Then you will want to disconnect the power connectors from all the devices and try it. There will be a connector with red, yellow, black, and white on the back of each device such as the hard drive and DVD drive. By disconnecting the power from these devices you can ensure one of them does not have a short or fault.
Most of the time the problem is simply the power supply. If you recently had a power surge or outage then your are probably out of luck. Power supplies are usually fairly cheap and easy to replace though so as long as your motherboard is still in good shape you should be fine.
In this particular case the computer stays on for a few seconds and/or shows the HP/Compaq logo you may want to try entering the BIOS using F1 for XP and F10 for Vista. If it stays in the BIOS with no problem then their is most likely a SW issue and a recovery maybe the best option for a quick fix.
