It sounds like the CPU is over heating. It probably has poor ventilation. Unplug the unit and open the side panel. Carefully vacuum all the dust inside. Be careful not to damage any electronics. You can use a small brush to loosen the dust before vacuuming. Good luck!

you bringing a marginal part or connection back up a working state. when it cools or voltage drops it goes to the non working state. hp power supplies are not good to begin with. replacing it will fix it till that one also fails

Power Supply is bad. Plain and Simple. Replace it. Regards, joecoolvette

Try Unpluging the power supply and press and hold the power button for about ten secs - leave it off for about two min and plug it back in and turn the computer on.

see if that work,

Thanks

plug your pc directly to your wall outlet and see if it turns on. If it works, then the problem is your power supply. If power supply has a reset button, press it and try again. If pc does not turn on when plugged to wall outlet, then power supply for pc may be out.

plase open the cpu & plug in the ram in the right order.

Ok, this is acting as if your MB is getting power but doing nothing with it. This very well could be a MB problem where something (unknown without looking at it) is fried. Just for grins, take the cmos battery out and let the pc sit for 1/2 to 1 hr before putting it back. If this does not work, I would contact HP for a replacement MB.

Here is a Compaq document will walk you thorough a fairly lengthy procedure that should solve your problem.
