HP Pavilion wont power up

This answer isn't going to help you any - but someone on Ebay is selling the same system, with the same problem. They comment that the system doesn't turn on and they don't know why. They are selling it for $85. I have the 8755c (didn't ship with XP), and it is still working fine. For the cost of a new motherboard for that system, you might consider buying a new desktop. Dells Outlet store has some pretty cheap desktops (~$300). Intel is coming out with new chips at the end of this month, so prices on the older models will also be coming down some.
My plan is to continue using my HP until it dies, then replace it :-)

Thanks I think I can buy a MB or a Processor for about $100, I just need to figure out which it is

Open your case and look at your motherboard, specifically, look for leaking or bulging capacitors. This is a common failure pattern, and they do tend to just quit. Generally, your processor and ram are fine, but you will need to replace the board if you have any popped caps.

This probably isn't the answer you want either....
Had the same problem with my sisterinlaw's Pavillion. Swapped out everything with another system & proved that it was the motherboard. Found it was cheaper to replace the box than to repair.

try this , pull the plug from the power supply and then hold the power button for at least one min , this will drain the compasitors that could be locking the relay in the off position , If you see the green light you are getting powet to the powere supply , This has worked for me quite a few time as I use to be HP support
