computer turns itself on after shutdown

Hello People,
My Windows XP computer mysteriously turns on by itself after I shut
it
down. Sometimes this happens after a few seconds or sometimes after
a
few minutes.
I've read other postings on this topic and some say that it might be
the wake on LAN or wake on ring feature in the BIOS. My computer is
not connected to a LAN, and I've disconnected the modem but it still
turns on.
I have an Abit NI8-SLI motherboard with a Pentium D 805 processor and
an Antec 520W power supply. It is a homebuilt system.
Could it be that the power supply is faulty? A few days ago, i
noticed that one of the loose power connectors arced against the
chassis while it was powered on (I had the case open) and it shut
down
automatically. Could I have damaged the power supply or motherboard?

Yes. Antec is one of these companies with shiny products,
good marketing and bad quality.

Should not, but knowing Antec, it might very well have.

I had a standoff for the motherboard that was in the wrong place, shorting
something out and causing the comp to turn itself on and off randomly.

Check your BIOS for "wake-on-lan". If it's enabled, disable it.

Go into the bios and make sure you do not have it set to wake up on Lan or
other stuff.

Try switching off the power strip and see if it can turn that back on.
