New PC won't boot and no post beep

Hi,

I've bought a new pc yesterday (AMD 2400 +, 512 Mb RAM, 64Mb AGP) i build.
Before to put HDD and DVD, i would test the motherboard with memory, cpu and
AGP graphic card, monitor and keyboard.
When i turned on the computer, only the cpu fan turned during 5 secondes and
then the computer stops. There was no beep, nothing appeared on the screen.
I verified all the connection at least 2000 times.
I removed the memory and then i've heard a long beep but the computer still
stopped.
I replaced the memeory and removed the graphic card, nothing.
Removed and replaced the cpu fan and processor.

This is not the first time i build a PC. I've got problem with HDD, Graphic
card, unplugged cable...
But never this problem.

I don't know what to do or what to test.

So please can you help me ?

Thanx in advance

Stef

Try it without anything and see if you can get the fans
to run. Then add parts one at a time.

Sorry for asking but you are sure you completely cleared the CMOS?
Sometimes
you have to wait ten minutes and make sure the power is unplugged
from the
wall outlet.

| Just an Idea:
|
| Clear the CMOS. At least here it works! When I made a change
to the
CMOS
| yesterday and went for a reboot I found I couldn't boot my new
computer.
| There wasn't even a beep although some lights went on for a
bit. I
| *thought*
| I wood have to clear the CMOS and checked the manual . The
manual said
to
| clear the CMOS when the computer doesn't boot, and said do so
by
| unplugging
| power and removing the battery for ten minutes. So I did. When
I
booted
| next
| time the computer worked although it wanted me to hit F4 to go
into
the
| CMOS
| and fix the clock and other configurations wiped when I
cleared the
CMOS.
|
| Your mobo may have another way to clear the CMOS etc. but it
might
work.
|
| This is because with all the different configurations you
pulled on
the
| mobo
| while testing the CMOS has 'sort of' jammed.
|
| My brother's computer's CMOS display corrupted when we were
shuffling
| around
| harddrives last week. On his computer I could clear the CMOS
by
shorting
| jumper pins. Once done the CMOS display at the beginning of
the boot
was
| fine.

If fans are not even turning then I would suspect either the power
supply has gone or something is shorting the +12V to ground, like a
plug or part of a board touching metal. Inspect the plugs, cable and
clearances.

Is the cpu fan connected some m/b won't boot with the cpu fan disconnected?
AGP card correctly seated? Good memory and seated? If you have a PCI
video card try that instead of the AGP. Switch memory positions or use
only one stick.

Pls post details about your m/b, memory and video card.
