I have an HP a630n computer. A week ago, I reinstalled Windows on it. I was planning on selling the computer, but the next day, the computer would not turn on. I took off the side case, and inspected the inside, looking for any loose cables, etc, nothing. The green light on the power supply is not even functioning. I unplugged the 24-pin plug from the power supply, and the green light lit up. But when I plug the 24-pin cable back in, the green light goes away. Your help would greatly be appreciated. If you need any more information, don't hesitate to ask. Thanks. I would really like to get this computer going again.

Tried swapping another PSU of same or greater output wattage? Did you inspect for any broken pins?

I agree with jhayz it sounds like a Powersupply issue to me. Take a look at HP's document on troubleshooting the Power Supply of this model by following the link below.

also with a computer that is this old before I purchased a new Power Supply I would check the Motherboard for swolen / leaking capacitors that are common for this age of computer. Folow the link below for what to look for.

only after verifying that your board does not have any other problems would I replace the Power Supply
