I have built and upgraded quite a number of PCs in the IBM ATX
architecture.

Today, I moved the internals of a computer that has been successfully
running Windows XP Pro for 2-1/2 years. That computer's internals include
an ASUS P3V4X Motherboard, 3 ATA-100 hard drives (all controlled by an
ATA/100 Promise PCI controller,) a CD-RW drive, 3 CD-ROM drives, a 3COM NIC,
a SoundBlaster PCI card, an AGP video card, and a 3 1/2" floppy drive.

After transferring all internals from my old cabinet to a new one, I powered
the computer up. It booted and started WindowsXP Pro successfully, though
prior to starting Windows XP Pro, the motherboard boot process indicated
that a problem existed with the floppy drive, which I bypassed by pressing
F1. The problem was easy enough to diagnose; somehow the power cable for
the floppy disk drive had come loose from its connector/socket. After WinXP
Pro finished its startup process successfully, I exited Windows by selecting
Start | Power Off | Power Off. The computer powered down normally.

After disconnecting the power cord from the back of the computer, I replaced
the power cable on the floppy drive's power connector. Then, I plugged the
power cord into the back of the computer and pressed the Power button.
However, nothing happened. I checked to be sure that the small wire from
the Power button was still plugged into the proper location on the
motherboard. It was. Nevertheless, the computer will not boot up.

For the moment, I'm not sure what's wrong. I don't know if the 300 Watt
power supply just happened to become defective at that time, or if something
is wrong with the motherboard.

So, I shall greatly appreciate your kind help in figuring out what's wrong.

When you unplugged the power cord from the power supply, is
it possible you tripped a circuit break, voltage switch or a
fuse?

Are you sure the wall socket is powered,too?

If you have a multimeter, check the PSU voltages.

Hi, Jim!

Thanks for your feedback. I sincerely appreciate your interest.

The wall socket is definitely powered.

I am not aware of any circuit breaker or fuse in the 300-watt power supply.
There is a red volt setting switch; it's set to 115. If there's a fuse or
circuit breaker of some sort on the ASUS P3V4X motherboard, I'm not aware of
it.

I forgot to mention that I don't have a multimeter or volt meter of any

Don't change the subject line, put the questions and answers
in the body, please.

PSU do have internal circuit protection, if you're sure the
wall outlet has power and nothing happens when you press the
power switch, some failure, perhaps a fuse, broken wire or
such is the likely problem.
Do any fans or lights work? Any beeps?

You can buy a simple tester/meter for the power supply for
$10-20, it might be a good investment and it can be used to
check many other things too. Radio Shack has a nice little
book on how to use a multimeter Google for "multimeter book
radio shack" or "how to use a multimeter."

Hello, again, Jim,

Nothing happens when I press the Power button; no fans, no beeps, nothing
whatsoever.

I will pickup a tester at Radio Shack today.

I don't understand the initials "PSU". What do they stand for?

Try the simple first.
It was working before and you only switched the floppy cable.
Perhaps you pulled or bumped a wire lose from the motherboard connections.
Like the ........Power button wiring to the motherboard........Check all
your connections.

Thanks stonekeyboards for your feedback.

I have double-checked all wiring connections to th motherboard; all are
properly connected, including the Power Switch connector and the ATX Power
supply connection to the ASUS P3V4X motherboard.

Hello, again, Jim;

This problem just gets curioser and curioser. I have double-checked all
wiring connections to the motherboard; all are properly connected, including
the Power Switch connector and the ATX Power supply connection to the ASUS
P3V4X motherboard.

I took your suggestion on getting the RS Multimeter. However, the folks
there were not aware of the How to Use book that you mentioned. So, I
checked Google and found guidelines for testing the 300 watt ATX Power
Supply. With the AC power cord from the wall socket plugged into the ATX
Power Supply, I set the Multimeter to 15 volts DC (the lowest setting
available on this Multimeter. I then used the black probe to probe one of
the black wires in an unused power connector coming from the power supply.
I used the red probe to probe the yellow wire in the power connector. I got
no reading at all. I then used the red probe to probe the red wire socket
on the power connector. Again, I got no reading. Incidentally, I did
install a good AAA battery in the Multimeter before getting started.

According to the guidelines I found on the article, that meant that the
power supply was dead and needed replacement.

So, I replaced it with as 400 watt, unswitched power supply and made all of
the appropriate connections to the motherboard and floppy drive, hard drives
and CD-ROMs

However, the computer still wouldn't start. Absolutely nothing happens
when I press the power button. No beep, no fans whirring, no lights flash.
Nada!

So I used the Multimeter to probe the 400 watt power supply's power
connector's black, yellow, and red wires with the Multimeter set to 15 DCV.
However, the needle did not budge from zero. It produced no reading
whatsoever.

Though it may be the case, I find it hard to believe that both power
supply's are defective.

I shall very greatly appreciate ay further ideas as to what might be keeping
this computer from starting.

With kindest regards

Dick Smith
