same situation
fixing it for a friend
I opened up the power supply after i noticed it clicking and blinking the green led on the power supply after I looked inside first thing I noticed was two medium size bulging and possibly leaking capacitors so I think that's the prob no blinking when its unplugged from the mother board and as soon as I plug it in it starts clicking and blinking.

Unless you have the skills and access to parts you can't easily repair stuff.

Replace what you suspect is bad.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

How did you open the Power Supply? You actually removed it from the case and tore it apart?

I would strongly urge you not to attempt repair of the power supply. If you make a mistake, and that is all to easy for an inexperienced person to do, you risk serious damage to the rest of the computer. It could also be dangerous.

As above, the power supply should be replaced. It was a cheap one that was included with the system so consider a better one, avoid the $20. ones and look to something closer to the $50. ones. Look for 80% efficiency, a little bit more power than you had (for future expansion), and all 12volt amperage on a single rail (not 2 or 3).

You have to be a little bit crazy to keep you from going insane.

So then, you have unplugged the main power connector to the motherboard while the power supply had AC current running through it?

If so, you MAY have damaged the motherboard. I can't say if the capacitors in a PSU are supposed to bulge or not because I haven't dismantled one. That is very dangerous. The capacitors can remain charged for long periods of time and can harm you.

At any rate, PSUs are not a consumer serviceable component.
