Rocky, disconnect the power connector from the PSU to the mobo,
then manually switch it on. If all the periph's power up, it's
probably good.
There's 2 wires you short ON AN ATX PSU ONLY, to power it up.
This bypasses the mobo's PWR ON switch header. See how here:
http://www.duxcw.com/faq/ps/ps4.htm . Jump, then remove it
after if powers up. Don't do this very long. Have a DMM handy
then check the voltages with it powering the periph devices.
Put the black neg lead to a black wire, and the red wires
should be about 5v, the yellow should be about 12v, orange
about 3.3v. More details here:

If while doing this the voltages are within spec and the periph
devices and fans are running, it's probably Ok.
If it's not a typical ATX layout (and it's probably not),
you'll have to watch out for what's what. Also if it's a
24-pin connector PSU, you may have to improvise on that info at
the URL's.

HI all. I can't test PSU under a load, but it is brand new. My
friend
bought it thinking that was the problem. I checked and it
works' but
that all I can say. It just don't do anything when you try
turning it
on. My guess is the board from reading the other e-mails.
Thanks guys.

Rocky for some reason I never received your original post.
What **exactly** is happening, nothing at all, totally dead?
Any clicks or any activity at all? If it is absolutely totally
D-E-A-D, how do you know for sure the PSU is ok? How did you
test it? They should be tested under a load.
If the CPU is dead, you should still get something starting up.
The mobo could be bad in such a way as to exhibit that totally
dead/nothing behavior. But I'd find out for SURE if the PSU is
ok first.

Hi Rocky,
I've seen about 50 eMachines come into the shop since 1999 or
so. At
least ninety percent had a blown power supply or motherboard or
both.
Statistically, the motherboard is bad if the machine is over 3
years old.
