I'm having problems that I'm pretty sure are related to my power
supply.

I installed a new dvd burner in my system. The system booted up fine.
It recognized the DVD player and installed it. It told me that I had
to reboot the system to complete the installation. I rebooted it and
it worked fine for about 5 minutes. After about 5 minutes after reboot
the system shut off just like I unplugged the computer. I was standing
near the computer but not actually using it while this happened.

The computer has not booted since. If you push the on switch,
absolutely nothing happens.
I have unpluged and repluged the computer into several different
plugs. I bought a new more powerful power supply and installed it but
the system is still dead. There is a light on the motherboard and
there is a light which goes on and off as I turn the computer on and
off with the dsl plug. So it appears that I am getting power. I
returned the new power supply and got another. And the exact same
thing happens with the 3rd power supply.

I had the exact same systems happened when I got the computer 2 years
ago. The original power supply failed, I installed a second, when I
brought it to a shop they installed a third power supply and told me
that the power supply I purchased was bad.

This all started when I installed a new DVD burner. Since the system
booted, installed the DVD player and then rebooted sucessfully, I doubt
that there was any problems with the DVD installation. I could have
overloaded the old power supply.

Is there anything else I can check?

Disconnect the new DVD drive and see what happens. If system runs normally,
return the DVD drive. If still dead, your system motherboard is likely bad.

Unplug everything but the motherboard and see if it boots up and gives any
kind of post message on your monitor.
If it does then connect the items, one at a time and confirm the system
boots, when it stops booting and presenting the post info then you may have
found our what item is loading the SMPS.
However, if it does not boot with just the motherboard connected then either
you have another bad SMPS or the motherboard took a hit and may need
replacing also.

My motherboard is an ASUS A7n8x-e Deluxe

I've tried unplugging all of the harddrives, dvd players and floppy
directly from the board. Nothing happens when I push the on switch. I
don't hear the fan start or anything. I haven't unplugged any of the
cards yet.

When you install a power supply, does anything else plug into the
motherboard besides the 20pin plug, or are there any reset switches on
the MB etc. ? My MB is about 3 years old so as far as I know I dont
need the new extra 4 pins that come with my power supply. I've
double/triple checked the 110/220 switch and the on/off switch on the
power supply. The only other thing on the power supply itself are the
plugs that plug into the MB and components.

The thing that confuses me is that I had the exact same thing happen
when I first installed the board about 3 years ago. The tech told me
that the replacement power supply that I installed was faulty and he
installed a third one and it worked. I'm wondering if there was some
other step I missed when I installed the power supply?
Since if its the power supply problem, I've bought 3 bad power supplies
in addition to the two that went bad. If its not the power supply, why
am I getting exactly the same symptoms on the same MB a second time?

Try this and try that and.... well that list is long and still does
not say what is wrong. You want to identify the problem now, and then
fix it. In but minutes with a 3.5 digit multimeter, we can identify
the problem AND then replace the suspect. Do not attach or disconnect
anything. Changing things may even exponentially complicate the
problem. That 3.5 digit meter is available for less than $20 in Sears,
Lowes, K-mart, Radio Shack, and Home Depot. That's the complex part.

With computer plugged into AC receptacle, use meter to measure
voltage on purple wire between power supply and motherboard (connect
probes to purple wire by pushing into nylon connector and other probe
to chassis). That voltage must be more than 4.87 VDC. If not, power
supply controller will not tell power supply to power on. Next measure
voltage on green wire. It must be more than 2 volts before switch is
pressed and must drop immediately to less than 0.8 volts when switch is
pressed. This tells power supply to turn on.

Next measure voltage on gray wire. It must rise to more than 2.4
volts within seconds after power switch is pressed. Again, you want to
see what happens when switch is pressed - not just long after switch is
pressed. This signal tells motherboard that power supply is OK.

If gray wire is good or bad, then move on to one red, orange, and
yellow wires. Measure each as switch is pressed. Within one second,
each should exceed 3.23, 4.87, or 11.7 volts DC. If any does not rise,
then find what ever on motherboard or peripherals is excessively
loading that voltage.

Not only do numbers help you to find a the suspect. Those numbers,
if posted, mean that your replies can include useful information.
Without numbers, then every reply will be only 'try this and try that';
also called shotgunning. These numbers can also identify an
intermittent failure before that failure occurs. Useful numbers
obtained in but two minutes means a useful reply; and no shotgunning.

Thank you for the detailed instructions. I'll try them tomorrow if I
get a chance and post the results. I read a few other post that
suggested using a meter but most of them did not give anywhere as clear
instructions on how to as you have.

I was kinda hoping that I'd forgotten or didn't know about an
instillation step. I've had that happen in the past, forgot to plug
the computer in sort of errors.

I was planning to upgrade the power supply anyhow so I tried that
first.

There are so many wires and connectors in front of the connection
between the power supply and the MB that I'll have to disconnect some
of them to get to it.

Hi...

One more suggestion, for what little it may be worth...

Take a good look, make sure that you haven't accidentally partially
dis-lodged one of the cards in your machine while you were installing
the dvd. AGP cards are particularly susceptible to being not fully
seated, and weird things result.

Take care.

Is it an Antec power supply? I've seen a lot of them die like that, I
just replaced my own with an Enermax recently after the Antec started
randomly shutting off.

Unplug the cards, I had my graphics card come partially unseated once
and the system wouldn't power up.

No, not from the motherboard. Unplug the *power connector* going from
the power supply to each of your drive devices. Is your PSU fan
spinning?

Make sure none of the cards are shorting to each other.

So do you still have the same intermittent. The system may work fine
for a while, then do some strange things. Even with a new supply, one
then repeats those same measurement in but a few minutes to so that
margin voltages today do not result in intermittet crashes next week.
