Lost Power to turn on ASUS A8n SLI

I came down to my computer today, tried to turn it on and could not get it
to power up. The green light on the motherboard is on, but activating the on
switch does not turn on the power. Help!

1) Try powering it off at the wall, and then back on again (this'll fix
some problems).

2) If you are halfway competent inside PCs try swapping the reset and
power switches (although it's most unlikely that one died). They are
both 'momentary contact' switches if we are talking a modern ATX PC
(beware AT powered systems don't work like that!). You could also just
briefly short the two pins the front panel power switch is connected to,
which is what turns the thing on.

3) Examine the motherboard for signs of leaking, bulging, or blown,
capacitors, the #1 cause of PCs dying (although they usually act flaky
first).

If none of those apply then you've probably got a dead motherboard or
cpu. You're into serious debugging, which involves removing practically
everything, and swapping in know good items for CPU, PSU, motherboard
etc. Depending on how old it is, it may be simper and cheaper to just
start over.

Google may be your friend, but groups.google.com posters definitely aren't.

Given it's an A8N-SLI I'm assuming it's not too old :-)

I had a bad Antec Neo PSU cause this on that board.. the +5VSB line got
so weak that it couldn't supply enough power to the board to power up.
It was fine until I powered the machine down and it actually needed the
standby power..
