Computer receives power for a second when plugged in then stops.

When I plug in my HP Envy the light on the back lights up green for about .25 seconds and then turns back off and stops receiving power. It doesn't respond to turning on and doesn't seem to be receiving power, thought not consistent. It does repeat this process every so often when I pull the power cable out and plug it back on.

EDIT: I just found that it stays on until I press the power button.

If you personally happen to be an electronics repair person, maybe you could fix. Diagnosing computer PSU's is not easy, and is different from the power supply systems in other types of electronic devices. But to take it to a pro shop and have them do the job is almost certain to cost more than buying a new PSU.

HOWEVER, your later post of the EDIT says you have discovered the light does stay on until the front button is pushed to start the computer. This MAY indicate that the problem is not the PSU, but instead is some other component in the computer that is drawing too much power. Now you have more possibilities to examine and diagnose. This means that just buying and replacing the PSU may NOT solve the problem. It can get expensive...

I don't really have the money to afford any computer parts anymore. Being a college student takes most of my funds. Is there any possibilities to fix it?

This means that just buying and replacing the PSU may NOT solve the problem. It can get expensive to guess and replace items until it works again. You need some help to diagnose the real problem. Got any buddies who are good at this and can help for free?
