Intel motherboard D845BGL won't boot
Z Man
me stumped.]
Just ordered this retail boxed motherboard, and retail boxed P4 1.6A. I
hooked up this stuff in a high quality tower case with 400w power supply,
AGP video card, nothing else plugged in. Hooked up the regular power
connector, plus the four pin connector that plugs in near the CPU. Attached
just the power switch wire. Plugged CPU fan connector into motherboard
I know I have power because there's a little green light inside that goes
on. However, nothing else happens. Tried reseating CPU, reseating memory
(two sticks DDR taken from another working system, tried both in both
slots), I get nothing at all. If I pull out the power cord, then put it back
in, the fan spins for about five seconds then stops.If I press the case
power switch, nothing at all happens (this is the only wire I have plugged
in, not yet using the reset switch, power LED,etc).
Ideas?

pins or the switch is faulty. You can check whether it's the switch by
simply shorting the pins.
If you have connected the switch to the wrong header then it's easily done
so don't be surprised because Intel use a strange pin-out which wasn't even
mentioned in the manual for one of their boards I used not so long ago, had
to find it (well hidden) on their website.

you have the six pin connector pluged in? Most P-4s require all three
connected.

. If you mean the rocker switch that's been on some power supplies for a
long time and has nothing to do with a p4 supple.
If its something else please inlighting(sp) me.

I have two power connectors, not three, at least as far as I can tell. There
the traditional standard power connector that's been on motherboards for
year, plus one additional four pin power connector that plugs in near the
CPU. It there's a third connector, I missed it. Where should I look?

I looked all over but I cannot locate such a switch.
I do get some indications of power. There is a little green 'standby' light
on the motherboard itself, and it lights up when I plug in the a/c power.
Also, if I unplug the a/c power connector from the wall, then re-insert it
and press the power on button on the front of the case, the fan spins for
about four or five seconds, then stops. If I press the power button again,
nothing happens. However, if I again unplug the a/c power and repeat the
process, the CPU fan will again spin for a few seconds before stopping.
This evening, I removed the entire motherboard from the case and tried
powering up, just in case something was shorting out. I got exactly the same
result. At this point, I am perplexed. I feel as if I am missing something
simple and obvious, but just what it is escapes me.

p8/p9 connectors on an AT power supply. To my knowledge the only boards
that do not use them are ASUS, who have a standard 4 pin Hard Drive
connector on them. From my experience it is usually located near one of the
other connectors.

Most motherboards don't in fact have this additional AT style connector. The
one you mention on the Asus boards is for the additional 12v rail for the
CPU, if your PSU is not P4 ready you can then still use an Asus P4 board by
just connecting the standard Molex connector to it.
I've used an Intel 845WN board that didn't have the AT type connector and my
current Asus board does not have one either, I'm not really sure what this
additional AUX connector is for but would suspect it is used when boards
have additional hardware onboard, LAN, SCSI etc....

I looked over the ATX 2.02 spec and could find very little about the AUX
connector other than it exsists. I agree that it is probably for additional
hardware. As for his problem of not booting, most motherboards I have seen
that have all three will not boot if only two of them are connected.
If the power connectors are not the problem, then next solution would be to
remove all unnecessary components (HDDs, CD-ROMs, Cards) and try it, if it
still doesn't boot then I would suspect CPU , motherboard, or power supply.
A bad CPU is very rare, I install about 20 P-4s a week and since they came
out I have had only one go bad, for no obvious reason either.

I'm in the process of selecting a new mobo to buy. One option was the
D845PT, however I noted that it supported every 478 pin p4 EXCEPT the
1.6A. The faster northwoods are supported. This is in the
downloadable manual addendum. I wasn't sure if it was really true but
perhaps it is!

I have the D845BG and 1.60A. The mb supports this CPU, doesn't it?

I think I already checked it, but I'll take another look.

every penny that went into the validation work. I have not seen a crash or
BSOD on this compo.
In "active monitor", my idle cpu temp. is about 29-30C, and when playing
fullscreen DVD, it maxed out at 33C.
