Computer boots after power supply restarts twice

My computer boots after the power supply restarts twice.

It seems that I have to unplug it for a while before restarting again.

I tried replacing the power supply.

Some of the wires from my old power supply to the motherboard were
discolored. It was a 4-pin connector.

Any ideas?

Take a look at http://www.badcaps.net/
If you see familiar pictures there, you have your answer.

That's very odd. Especially if you mean 'burned by over current'.
Are you sure your PC is not an ancient Dell type with
non-standard PSU wiring ?

You might want to check for a loose connector or corrosion on the connector.

A loose connector might be one that was not seated all the way or more
common one or more of the female socket of the connector is slightly
oversize so it is not "grabbing" the connector tightly on the
motherboard resulting in minor arching, voltage loss, and subsequent
heat build up.

You might want to unplug things and check for corrosion on the
motherboard connector, since you already tried another power supply.
Corrosion can cause voltage loss as well as excess heat build up in the
connector resulting in the discoloration. After this try the
replacement power supply again as the connector of the old power supply
may also need cleaning or tightening.

If nothing from the above resolves your current problem (no pun
intended) I'd try the other suggestions like reseating the memory
modules, removing all non-critical hardware as in CD/DVD, non-boot hard
drive(s), and any circuit cards that can be temporarily replaced by
using any built in motherboard features.

After buying a new CMOS battery for the motherboard, the computer is running
a little better. I can now restart successfully.

I'm still getting that hiccup with the power supply. I'm guessing it's just
a symptom now, that just won't go away.

While the computer works when plugged into the outlet, it's not working with
the surge protector. Maybe I need a new surge protector, or maybe the load
is just too big in my house of hunny.

Just kidding. It's the hard drive. Time to dig out that 5-year warranty.

You dont have a laser printer plugged into that surge protector do you?

No, but it did seem to work better without the printer plugged into the
computer

I thought the problem was the hard drive, because the computer seemed to
work fine with another hard drive, but the problem was actually the video
card. It was hard for me to test this because my onboard video doesn't seem
to be working. Maybe I need to set a jumper or something.

Looks like I have a couple of blown capacitors on the motherboard. One of my
USB ports doesn't seem to work. I have a Dell Inspiron 530 with a Foxconn
G33M02 motherboard.

Sparks come out of my outlet sometimes when I plug in the computer and
monitor. I'm not sure what that's about.

Oh, well. I got a brand spanking new video card, power supply, and hard
drive. I guess mechanical aptitude isn't all it's cracked up to be.
