HP media Center m8330f No power?

Specs: Windows Vista
I have a HP Pavilion m8330f No power. When I hit the start up button nothing happens at all. Ive checked the outlet using another unit and it's working. I turn the tower around where the power cord plugs in and sometimes when i connect a little green light just below the power supply will light for a split second and a couple of times the cooling fan has engaged, not enough to spin but it jerks just a small touch. Any help would be appreciated as it's not that old and a great machine

Sounds like the power supply is shot. Open the side panel and read the specs that are printed on the label. If you're going to buy a new one and attempt it yourself, buy a decent psu like the Corsair line. Look for a psu that has a single 12 volt rail as opposed to multiple rails. Here's an example.

Thanks grasshopper. I'm by no means a computer expert. I have taken the case off some of my older ones on occasion. I am pretty good at following directions. I've taken the side panel off and I can see the power supply. I'm assuming your a computer guy, if you were me and had my limited experience, would you do it yourself. Not responsible for my decision and if i break it i break it. Just trying to get a feel for the difficulty level. Thanks again

It's not hard. Pay attention to where all the wires connect. The first time I did this, I used a small piece of tape to label each one. Label them, remove the screws from the back of the case that hold the psu in and remove it. Slide the new one in and reconnect the wires. Before you go into the case, touch the chassis to ground yourself to prevent a static charge to the components. Difficulty level is about 4. Most of the wires on the new psu should have a label on them. Good Luck if you try it.

No joy. Replaced power supply and still no power. Same as before must get a small jolt because every couple of times i plug the cord in the cpu fan will jerk. Not spin, just move slightly. Any more idea's? Thanks in advance.
