New Built PC won't even POST

2_Loons

I can't seem to figure this out-
Athlon 900 mhz CPU
New Abit KG_7 raid mobo (Good battery volatge)
New G-force2 AGP Vid Adpt.
New DDR 2100- Ram (256)
New Sound card
New 10 gig Western digital HDD

The system will not POST. No beeps, No response from the monitor. Nothing.
The fans power up and the HDD spins up but thats as far as it gets.
I have tried a different (known good) PCI -VGA board and still nothing.
I've tried booting it with the bare minimuns -VID,MEM, HDD, FLOPPY and still
nothing.
I reseated all boards, rechecked jumper settings.
I'm stumped.
Can anyone recommend what I might be overlooking please?

Many thanks!

Fans can spin and lights glow - and still power supply does
not provide proper voltages. First verify that power is OK.
No "Power Good" signal from power supply means nothing will
work. It only takes but a few minutes - and no changing
hardware - using a 3.5 digit multimeter. Procedure detailed
in "Computer doesn't start at all" in alt.comp.hardware on
10 Jan 2004 or
http://tinyurl.com/2t69q

Once power supply is established as good (and motherboard is
controlling same properly), then move on to other reasons for
failure. For example, using too many conductive stand offs,
or is the single connection between motherboard and chassis
near where power connects? Are those other conductive
standoffs shorting to motherboard traces? But first take but
a few minutes to verify that power is within specs.

Disconnect the HD and floppy as well. The BIOS should show withouty them.
Maybe the memory to.
I had issues with the jumper settings on my HD and CD etc.

Check that they are set correctly. Master or Slave ......It may be trying to
sort them out.

Someone came to me with the same problem a couple of years ago. The case
was the type that needed risers at parts of it to raise the board from
the case, if you know what I mean. The guy who built it didn't realise,
and screwed the motherboard straight on.....so some parts of the board
were shorted, other weren't. In the end up the motherboard was
fried.....

Could be other silly oversights, like leaving the plastic sticker on the
heatsink, causing the CPU to overheat.

Some basic troubleshooting tips:-

Set up only motherboard, ,1 memory stick, CPU and VGA. If still no
beeps, remove VGA and try again. Next remove memory, and try only
motherboard and CPU. Most machines will give a POST error in the form of
a beep code if there is no memory. If you don't get a response this way,
there is a good chance that either the motherboard or CPU are fried.
(All of the above assume known good power supply)

The last thing I can think of is that your motherboard just doesn't like
the 900MHz CPU. I came accross a motherboard (Asus A7N266 possibly -
can't remember) last month that said it wouldn't run a CPU slower than
1000 MHz.

Good luck. I hope this was of some help.

H,

When I built my first PC I had the same problem... it was an ABIT mobo.
I just switched the RAM from slots and that fixed the problem.

A dead CPU gives those symptoms...

I've had this problem. Does it shut down after a few seconds too? What power
supply are you using? If you used an older box from an old system it is
probably the power supply. The new MBs want the newer PSs made for them. If
it's an old box, you'll need one eventually anyway. Oh...and you'll have to
reset the MB too.

Can you borrow some ram from a friend and try that, I had a similar
issue a few weeks back where the fans would spin up but the computer
would not post, I took the computer to the workshop and they replaced
the ram and off it went.

Yeah, I was afraid of that.
I tried everything. I guess the next step is to spring for a new one.
Thanks!

Have you tried hitting the 'Reset' button?
I have to do that. I wait 10-15 secs. after power-on to make sure all the
HDs, etc. are up to speed then hit Reset and then it immediately starts to
POST.
Easy enough to try, anyway.

Have you discharged the CMOS Memory? Usually this involves unplugging the
whole computer (killing _all_ power supplies), moving a jumper to two
specific pins on a header, and then moving it back to its normal position,
power on, ... ASAP, reset the CPU speed, buss speed, etc.

Sure did. Didn't help.

I had the same thing happen to me; it was the damned little "slide switch" on
the PS being set at the wrong position .

This motherboard is very picky about RAM, the only way I could get
beyond this problem was too re-seat the memory by pushing down VERY
hard while the motherboard was on a sturdy surface!

HTH!

Makes sense and I did try that but, even with the RAM not being seated
properly, I would expect a beep code.

Hi
My new system was dead apart from a light flash for one sec on the DVD, I
unplugged everything and plugged it back in and all was okay. Although the
floppy drive didnt work.

(1) Clear the CMOS.

(2) Disconnect the power supply from the motherboard for a short
period of time, then reconnect.

(3) You've reseated the cards, but have you reseated the motherboard
itself? I recently had this happen and it turned out that the
network card backplane was touching the motherboard and the case.
